It was a fabulous week of clear skies and dancing auroras in and around Yellowknife in Canada’s North.
For the second year in a row I traveled due north from home in Alberta to visit Yellowknife, capitol of Canada’s Northwest Territories. At a latitude of 62° North, Yellowknife lies directly under the auroral oval and so enjoys views of the Northern Lights on almost every clear night.
During my 8-night stay from September 3 to 10 almost every night was clear and filled with auroras.
Somba K’e Park
The Lights can be seen even from within the downtown core, as the opening image shows, taken from the urban Sombe K’e Park looking over Frame Lake and the Prince of Wales Museum.
The Museum is lit with rippling bands of coloured light that emulate the aurora borealis.
A favourite urban site for viewing the Lights is the Pilot’s Monument lookout in the middle of Yellowknife’s Oldtown district. This panorama sweeps from northeast at left to west at far right, looking mostly south over the downtown core.
This night even the urban lights were not enough to wash out the Lights as they brightened during a brief substorm.
Another good urban site that gets you away from immediate lights is the open spaces of Rotary Park overlooking the houseboats anchored in Yellowknife Bay. This panorama again sweeps from east to west, looking toward to the waxing Moon low in the south.
Again, despite the urban lights and moonlight, the Lights were spectacular.
The main viewing sites for the Northern Lights are down Highway 4, the Ingraham Trail east of the city away from urban lights.. One of the closest stops is a parking lot on the shore of a backwater bay of Prosperous Lake. It’s where many tourist buses stop and unload their passengers, mostly to get their selfies under the Lights.
But with patience you can get your own photos unencumbered by other lights and people, as I show below.
On one of my nights I stopped at Prosperous on the way to sites farther down Ingraham Trail to catch the twilight colours in the stunningly clear sky.
This small lake and picnic site farther along the Trail serves as a great place to shoot the Lights reflected in the calm waters and looking north. I spent one of my nights at Madeline Lake, a popular spot for local residents to have a campfire under the Lights.
And it’s popular for tour buses, whose headlights shine out across the lake as they arrive through the night, in this case casting my long shadow across the misty lake.
However, again with patience it is possible to get clean images of the aurora and its reflections in the lake.

Farther down the Trail is a spot the tour buses will not go to as a visit to the Ramparts waterfall on the Cameron River requires a hike down a wooded trail, in the dark with bears about. Luckily, my astrophoto colleague, amateur astronomer, and local resident Stephen Bedingfield joined me for a superb shoot with us the only ones present at this stunning location.
The view looking the other way north over the river was equally wonderful. What a place for viewing the Northern Lights!
The view from a viewpoint early on the trail down to the Ramparts and overlooking the Cameron River yielded a superb scene with the low Moon and twilight providing the illumination as the Lights kicked up early in the evening.
A favourite spot is the major camping and boat launch area of Prelude Lake Territorial Park. But to avoid the crowds down by the shoreline, Stephen and I hiked up to the overlook above the lake looking north. A few other ardent photographers joined us. This was another spectacular and perfect night.
September is a superb time to visit as the lakes are still open and the autumn colours make for a good contrast with the sky colours.
The panorama below takes in the Big Dipper at left, Capella at centre, and with the Pleiades and Hyades rising at right of centre.
I used the 8mm fish-eye lens to capture the entire sky, the only way you can really take in the whole scene on camera. When the Lights fill the sky you don’t know which way to look or aim your camera!

There are many other scenic spots along the Trail, such as Pontoon Lake, Reid Lake, and Tibbitt Lake at the very end of Ingraham Trail. For images and movies I shot last year at Tibbitt Lake, see my blog post at Aurora Reflections in Yellowknife.
But in my 8 nights in Yellowknife this year I managed to hit many of the key aurora spots for photography and viewing. I recommend a visit, especially in September before autumn clouds roll in later in the season, and while the lakes are not frozen and nighttime temperatures are mild.
Here’s a 3-minute music video of clips I shot from all these sites showing the motion of the Lights as it appeared to the eye in “real-time,” not sped up or in time-lapse.

As I do a couple of times a year, earlier this month I was cruising the coast of Norway chasing the Northern Lights – successfully!
One of my “retirement gigs” is to serve as a lecturer for the educational travel company Road Scholar (formerly Elderhostel) on some of their aurora cruises along the Norwegian coast on one of the Hurtigruten ferry ships.
This time, as I was last autumn, I was on Hurtigruten’s flagship coastal ferry, the m/s Trollfjord.
Our tour group was treated to five fine nights with auroras, an unusually good take out of the 12-day round trip cruise from Bergen to Kirkenes and back to Bergen. Our first look, above, was on February 27, but through cloud.
But after we reached the top end at Kirkenes and turned around for the southbound voyage, skies cleared remarkably. We had a wonderful four clear days and nights in a row, all with Northern Lights.
The best show was March 1, and when we were in port in the northern coastal village of Båtsfjord. The Lights danced overhead in the best show I had seen from Norway.
The next night we got a good show while we were in the port of Skjervøy.
As we continued south we emerged out from under the auroral oval zone, placing the Lights to the north, back in the direction we had come from.

Equally spectacular in my mind were some of the sunsets and twilight skies we enjoyed as we sailed through the Lofoten Islands, including on our visit to the narrow Trollfjord fjord for which the ship is named.
On our aurora nights I mostly shot “real-time” video of the Lights, using the low-light capability and 4K functions of the Sony a7III camera. The result is a music video linked to below.

For 11 non-stop nights in February we had clear skies and Northern Lights in Churchill.
Every year in winter I visit Churchill, Manitoba to attend to groups of aurora tourists at the Churchill Northern Studies Centre. Few groups (indeed only two over the 35 years the program has been offered) go away having not seen the Lights during the 5-night program.
But this year was the opposite exception. Even locals were impressed by the run of clear nights and displays in early February. It was non-stop Northern Lights!
Having auroras in Churchill isn’t unusual. It is located right under the auroral oval, so if it’s clear it would be unusual not to have some level of auroral activity.
But particles from a coronal hole at the Sun fired up the lights and gave us good shows every night, often starting early in evening, rather than at midnight as is typically the case. The shows pre-empted my evening lectures!
With shows every night, people soon got pretty fussy about what they’d get excited about. Some nights people viewed displays just from their bedroom windows!
Displays that on night one they would be thrilled with, by night four they were going back to bed awaiting a call later when “it gets really good!”
While auroras were active every night, the Lights showed little in the way of varied colours. Notably absent was any of the deep red from high altitude oxygen. The aurora particles were just not energetic enough I presume, a characteristic of solar minimum displays.
Increasingly, as we enter into the depths of solar minimum, with a prolonged lull expected for the next few years, aurora chasers will have to travel north to the Arctic and to the auroral oval to see displays on demand. The Lights won’t come to us!
We did see fringes of pink at times along the bottom of the auroral curtains from glowing nitrogen molecules, but even this was subtle to the eye, though obvious to the camera.
The nitrogen pinks are usually accompanied by rapid dancing motions that are amazing to watch.
The music video linked to below provides the best view of what we saw. It is made entirely of real-time video, not time-lapses, of the Lights as seen over several nights from the Studies Centre.
The video is in 4K, so do click through for the best viewing. And the Vimeo page provides more details about the video and the techniques.
The Northern Lights are amazing from Yellowknife, in Canada’s Northwest Territories.
A handful of locations in the world are meccas for aurora chasers. Yellowknife is one of them and, for me, surprisingly accessible with daily flights north.
In a two-hour flight from Calgary you can be at latitude 62° North and standing under the auroral oval with the lights dancing overhead every clear night.
The attraction of going in early September, as I did, is that the more persistent clouds of late autumn have not set in, and the many lakes and rivers are not yet frozen, making for superb photo opportunities.

Lakes down Highway 4, the Ingraham Trail, such as Prosperous, Prelude, and Pontoon are popular spots for the busloads of tourists who fly in every year from around the world.
On one magical night I and my local host and guide, Stephen Bedingfield, went to the end of the Trail, to where the Ice Road begins, to Tibbitt Lake, and had the site to ourselves. The aurora was jaw-dropping that night.
On other nights with less certain prospects I stayed in town, and still got a fine show on several nights, the Lights so bright they show up well even from within urban Yellowknife.

On another night we chased into clear skies down Highway 3 to the west, to a rocky plateau on the Canadian Precambrian Shield. Even amid the clouds, the aurora was impressive.
But it was the night at Tibbitt that was the highlight.
Here is the finale music video from movies shot that night, September 8, 2018, with two cameras: the Sony a7III used to take “real-time” 4K videos of the aurora motion, and the Nikon D750 used to take time-lapses.

One of my aurora images now appears on a new stamp issued by Canada Post to mark the 150th Anniversary of the Royal Astronomical Society of Canada.
It is always a treat to see one of your images in print, but this is a rare privilege indeed. On June 29 Canada Post unveiled a new set of astronomy stamps, one of which features an aurora image from me, shot March 14, 2016 from the Churchill Northern Studies Centre, in Churchill, Manitoba. I shot it from the second floor observing deck, looking east to the rising sky.
The other stamp features a Milky Way image shot by fellow RASC member Matt Quinn taken from the Bruce Peninsula, Ontario.
If you view the stamps under UV “black light” more image information is revealed!
The stamps were issued to mark the 150th Anniversary of the Royal Astronomical Society of Canada, which began as an exclusive “gentlemen’s club” in Toronto in 1868. It is much more inclusive today, as it should be, with a membership of 5500 people from across Canada.
The stamps were unveiled at a ceremony at the RASC’s annual General Assembly, this year held in Calgary where I live. Representatives from Canada Post, and of course the RASC executive were in attendance.
This shows (L to R): me, David Foote (author, eclipse chaser, and member of the Stamp Advisory Committee), Chris Gainor (incoming RASC President), and Colin Haig (outgoing RASC President) at the unveiling. Matt Quinn was not able to attend. All those present (including members of the local Philatelic Society) received first day covers which David and I autographed.
This was certainly a great honour, a once-a-lifetime event I’m sure. I am grateful to the RASC officials such as Randy Attwood who lobbied for the stamp issue, a process that began three years ago.
I was first contacted by Canada Post in October 2016 though the final image was not selected until October 2017. Since then, its use was to be kept secret until the “Big Reveal” unveiling at the General Assembly. For the most part, it was!
This is a shot I took of some of my fellow RASC members and friends from across Canada enjoying me taking a picture of them at the ceremony at the University of Calgary.
The strange aurora named Steve put on a show on Sunday, May 6.
The past weekend was a good one for Northern Lights here in Alberta and across western Canada.
A decent display lit the northern sky on Saturday, May 5, on a warm spring evening. I took in that show from a favorite spot along the Red Deer River.
The next night, Sunday, May 6, we were hoping for a better show, but the main aurora never amounted to much across the north.
Instead, we got a fine showing of Steve, an unusual isolated arc of light across the sky, that was widely observed across western Canada and the northern U.S. I caught his performance from my backyard.
Popularized by the Alberta Aurora Chasers Facebook group, Steve is the fanciful name applied to what still remains a partly unexplained phenomenon. It might not even be a true aurora (and it is NOT a “proton arc!”) from electrons streaming down, but a stream of hot gas flowing east to west and always well south of the main aurora.
Thus Steve is “backronymed” as Strong Thermal Emission Velocity Enhancement.
To the eye he appears as a grey arc, not doing much, but fading in, slowly shifting, then fading away after 30 to 60 minutes. He doesn’t stick around long.
The camera reveals his true colours.
This is Steve to the west, displaying his characteristic pink and white tints.
But overhead, in a fish-eye lens view, he displayed ever so briefly another of his talents – slowly moving fingers of green, called a picket fence aurora.
It was appropriate for Steve to appear on cue, as NASA scientists and local researchers who are working on Steve research were gathered in Calgary to discuss future aurora space missions. Some of the researchers had not yet seen Steve in person, but all got a good look Sunday night as they, too, chased Steve!
I shot a time-lapse and real-time videos of Steve, the latter using the new Sony a7III camera which can shoot 4K videos of night sky scenes very well.
The final video is here on Vimeo.

With summer approaching, the nights are getting shorter and brighter, but we here in western Canada can still see auroras, while aurora destinations farther north are too bright and lack any night skies.
Plus our latitude south of the main auroral oval makes western Canada Steve country!
The skies of Norway provided superb nights of Northern Lights as I sailed the coast.
As I did last autumn, I was able to join a cruise along the Norwegian coast, instructing an aurora tour group from Road Scholar. We were on one of the Hurtigruten ferry ships that ply the coast each day, the m/s Nordnorge, on a 12-day trip from Bergen to Kirkenes at the top end of Norway, then back again to Bergen.
In all, we had three very clear nights, with good auroras on two of those nights. Several other nights had bright auroras but seen through broken cloud.
All observing and photography is done from the ship deck as we sailed among the fjords and sounds along the coast.
The best night was an all-sky display on March 14 seen from north of Tromsø as we sailed back south from our farthest north of 71° latitude.
Earlier, on the trip north, we had a great night as the aurora danced over the Lofoten Islands and we entered the Trollfjord. There is no finer scenery on Earth for framing the Lights.
As is the custom, the captain enters the fjord by searchlight, a scene depicted below.
I shot very few time-lapses on this trip (unlike my trip in October 2017, which you can see in a music video at a previous blog post).
However, here’s a short music video of two clips I did shoot, including a time-lapse of us approaching the Trollfjord entrance.
As we sailed south, we left the aurora behind. Our last look was of the arc of the auroral oval across the north, seen from south of Rorvik.
However, for several nights prior we had been under the auroral oval and the Lights had danced for us over the sky.
Norway is one of the world’s best sites for seeing the Northern Lights – the “nordlys” – and taking a Hurtigruten cruise along the coast is a great way to see the Lights and incredible scenery that changes by the minute.
For the past three weeks I chased the “nordlys” – the Northern Lights – along the coast of Norway up to a latitude of 71° North.
As I type this blog our ship, the Hurtigruten ferry the m/s Nordlys, is rocking and rolling as we cross the Froy Sea off the southern coast of Norway on the way south to Bergen.
We’re completing a cruise up and down the Norwegian coast, the second of two consecutive 11-day cruises I took this autumn as an enrichment lecturer on aurora cruise tour packages offered by the U.S.-based Road Scholar tour company.
It’s been a superb chase up and down the coast – twice! – to catch the Lights. We got a total of 8 clear nights of aurora out of 22, not a bad tally for this time of year.
Here’s a gallery of images, all shot from the ship using a fast lens and high ISO speeds to keep exposures down to about 1 second to minimize blurring from the ship movement.

The scene as the m/s Nordlys exits the narrow Trollfjorden fjord, with the ship’s spotlights lighting the walls of the narrow fjord and with the aurora dancing. Ahead lies the winter sky with Taurus and the Pleiades rising. This was a magical moment indeed, one of the best of the Norway cruise. This is a single 0.8 sec exposure with the 14mm Sigma Art lens at f/1.8 and Nikon D750 at ISO 6400.
Aurora in the moonlight from a nearly Full Moon over the Barent’s Sea off the north coast of Norway, November 5, 2017. This was a very weak Kp 0 to Kp 1 display, yet still showed up in the moonlight.

A wisp of aurora appears in a break in the clouds as the m/s Nordlys enters Trollfjorden fjord in the Lofoten Islands in Norway, on November 8, 2017. It was actually raining when I took this shot but a major auroral storm was underway and we got a brief glimpse of a curtain as we entered this spectacular and narrow fjord. Then the rain clouds closed in. The bright lights are the ship’s searchlights lighting the walls of the narrow fjord. The white at top is the ship’s smoke. This was from the aft deck looking astern. This was with the 12mm Rokinon fish-eye lens at f/2.8 for 1.6 seconds with the Nikon D750 at ISO 6400.
One of the most memorable nights was on the first cruise when we sailed into the narrow Trollfjorden fjord in the dark with just the ship’s spotlights lighting the fjord walls only metres away from the ship. Above us, the Northern Lights danced. Unforgettable!
The Hurtigruten line operates daily sailings up and down the coast, from Bergen to Kirkenes, up into the auroral oval, which in this part of the world lies at a high latitude above the Arctic Circle. However, the warm gulf stream current keeps the water from freezing and the coast far milder than would be expected for such a high latitude.
This is a trip that should be on the bucket list for all aurora chasers.
October has brought clear skies and some fine celestial sights. Here’s a potpourri of what was up from home.
We’ve enjoyed some lovely early autumn weather here in southern Alberta, providing great opportunities to see and shoot a series of astronomical events.
On October 5, Venus and Mars appeared a fraction of a degree apart in the dawn twilight. Venus is the brightest object, just above dimmer but red Mars. This was one of the closest planet conjunctions of 2017. Mars will appear much brighter in July and August 2018 when it makes its closest approach to Earth since 2003.
Satellites: The Space Station
The Space Station made a series of ideal evening passes in early October, flying right overhead from my site at latitude 51° N. I captured it in a series of stacked still images, so it appears as a dashed line across the sky. In reality it looks like a very bright star, outshining any other natural star. Here, it appears to fly toward the rising Moon.
Often appearing brighter than even the ISS, Iridium satellite flares can blaze brighter than even Venus at its best. One did so here, above, in another time-lapse of a pair of Iridium satellites that traveled in parallel and flared at almost the same time. But the orientation of the reflective antennas that create these flares must have been better on the left Iridium as it really shot up in brilliance for a few seconds.
Little in the sky beats a fine aurora display and we’ve had several of late, despite the Sun being spotless and nearing a low ebb in its activity. The above shot is a composite stack of 200 images, showing the stars circling the celestial pole above the main auroral arc, and taken on Friday the 13th.
This frame, from some 1300 I shot this night, October 13, captures the main auroral arc and a diffuse patch of green above that pulsed on and off.
You can see the time-lapse here in my short music video on Vimeo.
Friday the 13th Aurora from Alan Dyer on Vimeo.
It’s in 4K if your monitor and computer are capable. It nicely shows the development of the aurora this night, from a quiescent arc, through a brief sub-storm outburst, then into pulsing and flickering patches. Enjoy!
What all these scenes have in common is that they were all shot from home, in my backyard. It is wonderful to live in a rural area and to be able to step outside and see these sites easily by just looking up!
I’ve assembled a music video of time-lapse clips and still images of the fine aurora of September 27, with Steve making a cameo appearance.
The indicators this night didn’t point to a particularly great display, but the sky really performed.
The Northern Lights started low across the north, in a very active classic arc. The display then quietened.
But as it did so, and as is his wont, the isolated arc that has become known as Steve appeared across the south in a sweeping arc. The Steve arc always defines the most southerly extent of the aurora.
Steve faded, but then the main display kicked up again and began to fill the sky with a post-sub-storm display of pulsing rays and curtains shooting up to the zenith. Only real-time video can really capture the scene as the eye sees it, but the fast time-lapses I shot do a decent job of recording the effect of whole patches of sky turning on and off.
The display ended with odd pulsing arcs in the south.
Here’s the video, available in 4K resolution.
Alberta Aurora (Sept. 27, 2017) from Alan Dyer on Vimeo.
The Northern Lights dance in the solstice sky over a prairie lake.
This was a surprise display. Forecasts called for a chance of Lights on Saturday, June 24, but I wasn’t expecting much.
Nevertheless, I headed to a nearby lake (Crawling Lake) to shoot north over the water, not of the Lights, but of noctilucent clouds, a phenomenon unique to the summer solstice sky and our latitudes here on the Canadian prairies.
But as the night darkened (quite late at solstice time) the aurora began to appear in the deepening twilight.
I started shooting and kept shooting over the next four hours. I took a break from the time-lapses to shoot some panoramas, such as the headline image at top, capturing the sweep of the auroral oval over the lake waters.
Just on the horizon you can see some noctilucent clouds (NLCs) as well – clouds so high they are lit by the Sun all night long. NLCs sit at the same height as the bottom of the auroral curtains. But they appear here lower and much farther away, which they likely were, sitting farther north than the auroral band.
I also shot this 360° panorama (above) capturing the arc of the aurora and of the Milky Way. This is a stitch of 8 segments with a 14mm lens mounted in portrait mode.
I’ve assembled the several time-lapse sequences I shot into a short music video. Check it out on Vimeo here. Click through to the Vimeo page for more technical information on the video sequences.
As always click HD, and relax and enjoy the dancing lights over the calm waters of a prairie lake on a summer evening.
No one predicted this spectacle. But on May 27 the last-minute warnings went out to look for a fabulous show as night fell.
And what a show it was! As darkness fell the sky was lit with green curtains. After midnight the curtains converged at the zenith for that most spectacular of sky sights, a coronal burst.
As the night began I was at the Rothney Observatory helping out with the public stargazing night.
We saw the Space Station rise out of the west over the Rockies and pass through the Northern Lights.
It then headed off east, appearing here as the streak amid the Lights and light pollution of Calgary.
To continue to shoot the display I, too, decided to head east, to home. I should have gone west, to the mountains.
I drove through rain to get home, and missed the peak of the display, judging by images from others in the Rockies, and those to the north.
But as I got home clouds began to clear enough for a glimpse of the Space Station, on its next pass, flying overhead, again through the aurora. I wonder what the astronauts might have been seeing looking down.
From home, I caught another bright sub-storm outburst to the north, as the curtains suddenly exploded in brightness and rapid motion, with characteristic pink fringes at the bottoms, from nitrogen molecules.
What impressed me about this display was the smell! Yes, you see auroras and some claim to hear them. But this display is one I’ll remember for the springtime scent of lilacs in the night air as the Lights danced.
The Great Aurora of May 27 from Alan Dyer on Vimeo.
Here is a short music video of several time-lapse sequences I shot, of the sub-storm then post-storm subsidence into the patchy flaming and flickering effect that we often see at the end of a great display. And this was certainly one of them.
We southerners were treated to the class of display you usually have to travel north the Arctic and auroral oval to see.
Stargazers in western Canada will have seen him – Steve, the odd auroral arc.
There’s been a lot of publicity lately about an unusual form of aurora that appears as a stationary arc across the sky, isolated from the main aurora to the north. It usually just sits there – motionless, featureless, and colourless to the eye, though the camera can pick up magenta and green tints.
We often see these strange auroral arcs from western Canada.
In lieu of a better name, and lacking a good explanation as to their cause, these isolated arcs have become labelled simply as “Steve” by the aurora chasing community (the Alberta Aurora Chasers Facebook group) here in Alberta.
In a gathering of aurora chasers at Calgary’s Kilkenny Pub, aurora photographer extraordinaire and AAC Facebook group administrator Chris Ratzlaff suggested the name. It comes from the children’s movie Over the Hedge, where a character calls anything he doesn’t understand “Steve.” The name has stuck!
The 270° panorama from March 2, 2017 shows Steve to the west (right) and east (left) here, and well isolated from the main aurora to the north.
This is the view of that same March 2, 2017 arc looking straight up, showing Steve’s characteristic gradient from pink at top though white, then to subtle “picket-fence” fingers of green that are usually very short-lived.
The view above is Steve from exactly 6 months earlier, on September 2, 2016. Same features. I get the impression we’re looking up along a very tall but thin curtain.
Another view of the September 2, 2016 Steve shows his classic thin curtain and gradation of colours, here looking southeast.
Looking southwest on September 2, 2016, Steve takes on more rippled forms. But these are very transient. Indeed, Steve rarely lasts more than 30 minutes to an hour, and might get bright for only a few minutes. But even at his brightest, he usually looks white or grey to the eye, and moves very slowly.
Here’s a classic Steve, from October 1, 2006 – a white featureless arc even to the camera in this case.
So what is Steve?
He is often erroneously called a “proton arc,” but he isn’t. True auroral proton arcs are invisible to the eye and camera, emitting in wavelengths the eye cannot see. Proton auroras are also diffuse, not tightly confined like Steve.
Above is Steve from August 5, 2005, when he crashed the Saskatchewan Summer Star Party, appearing as a ghostly white band across the sky. But, again, the camera revealed his true colours.
Steve Auroras in 2015 from Alan Dyer on Vimeo.
Here are a couple of time-lapses from 2015 of the phenomenon, appearing as an isolated arc overhead in the sky far from the main auroral activity to the north. I shot these from my backyard in southern Alberta. In both clips the camera faces north, but takes in most of the sky with a fish-eye lens.
In the first video clip, note the east-to-west flow of structure, as in classic auroras. In the second clip, Steve is not so well-defined. Indeed, his usual magenta band appears only briefly for a minute or so. So I’m not sure this second clip does show the classic Steve arc.
The origin and nature of Steve are subjects of investigation, aided by “citizen science” contributors of photos and videos.
Local aurora researcher Dr. Eric Donovan from the University of Calgary has satellite data from the ESA Swarm mission to suggest Steve is made of intensely hot thermal currents, and not classic electrons raining down as in normal auroras. He has back-acronymed Steve to mean Strong Thermal Emission Velocity Enhancement.
Learning more about Steve will require a unique combination of professional and amateur astronomers working together.
Now that he has a name, Steve won’t be escaping our attention any longer. We’ll be looking for him!
The solar winds blew some fine auroras our way this past week.
Oh, that I had been in the North last week, where the sky erupted with jaw-dropping displays. I could only watch those vicariously via webcams, such as the Explore.org Northern Lights Cam at the Churchill Northern Studies Centre.
But here in southern Alberta we were still treated to some fine displays across our northern sky. The image below is from March 1, from my rural backyard.
The Sun wasn’t particularly active and there were no coronal mass ejections per se. But a hole in the corona let a wind of solar particles through to buffet our magnetosphere, stirring up geomagnetic storms of Level 4 to 5 scale. That’s good enough to light our skies in western Canada.
Above is the display from March 2, taken over a frozen pond near home. I like how the Lights reflect in the ice.
This night, for about 30 minutes, an odd auroral form appeared that we see from time to time at our latitudes. A wider panorama shows this isolated arc well south of the main auroral oval and forming a thin arc stretching across the sky from west to east.
The panorama above shows just the western and eastern portion of the arc. Overhead (image below) it looked like this briefly.
Visually, it appeared colourless. But the camera picks up this isolated arc’s usual pink color, with a fringe of white and sometimes (here very briefly) a “picket-fence” effect of green rays.
This is the view of the isolated arc to the west. Erroneously called “proton arcs,” these are not caused by incoming protons. Those produce a very diffuse, usually sub-visual glow. But the exact nature of these isolated arcs remains a mystery.
As we head into solar minimum in the nest few years, displays of Northern Lights at lower latitudes will become less frequent. But even without major solar activity, last week’s displays demonstrated we can still get good shows.
The Northern Lights once again performed beautifully from Churchill, Manitoba, making the sky dance with colours.
As I do each winter, I spent time in Churchill, Manitoba at the wonderful Churchill Northern Studies Centre, attending to groups of “aurora tourists” there to check an item off their bucket list – seeing the Northern Lights.
In the 30 years the courses have been presented only one group has ever come away not seeing the Lights. Well, make that two now. A bout of unseasonably warm weather in my first week brought clouds every night. Mild temperatures to be sure. But we want it to be -25° C! That’s when it is clear.
Our first clear night was very clear, affording us a wonderful view of the winter Milky Way before the Lights came out. Such a view is unusual from the North, as the Lights usually wash out the sky, which they did later this night. Even here, you can see some wisps of green aurora.
Normal temperatures didn’t return until week 2 of my stay. The second group fared much better, getting good displays on 4 of their 5 nights there, more typical of Churchill.
A few determined die-hards from Group 1 (here shooting the Lights) stayed on a couple of more nights, and were rewarded with the views they had come for. They were happy!
In the images here, at no time did the auroral activity exceed a level of Kp 3 (on a scale of 0 to 9) and was often just Kp 1 or 2. Farther south no one would see anything. But at latitude 58° N Churchill lies under the auroral oval where even on quiet nights the aurora is active and often spectacular.
In speaking to a Dene elder who presents a cultural talk to each of the CNSC groups, Caroline said that to the Dene of northern Canada their word for the Lights translates to “the sky is dancing.” Wonderful! It did for us.

This music video presents a montage of time-lapse movies I shot over four nights, from January 25 to 29, 2017. They provide an idea of what we saw under the dancing sky.

It was a perfect night at a dark site in southern Alberta. The Milky Way shone to the south and aurora danced to the north.
I had scouted out this location in June and marked it on my calendar to return in the fall when the centre of the Milky Way would be well-placed to the southwest.
The site is Police Outpost Provincial Park, named for the North West Mounted Police fort that once occupied the site, guarding Canada’s sovereignty in the late 1800s.
One result from the night of shooting is the opening image, the first frame from a time-lapse taken while deep blue twilight still coloured the sky. The main peak is Chief Mountain in Montana.
To the north an aurora display kicked up over the lake. While it never got very bright, it still provided a photogenic show over the still waters.
The waters were calm on this windless night (rare for southern Alberta), and so reflected the stars and Northern Lights beautifully.
Here, the Big Dipper reflects in the lake as we look north to the Lights. The movie below compiles still images and two time-lapse sequences, of the Lights and Milky Way. The sounds are the natural sounds I recorded on site, as flocks of geese were getting ready to migrate and the owls hooted.

With the harvest in full swing, the aurora and Moon lit the fields on a clear September evening.
This night, September 19, showed prospects for a good display of Northern Lights, and sure enough as it got dark a bright, well-defined arc of Lights danced to the north.
I headed off to some photogenic spots near home, on the prairies of southern Alberta. By the time I got in place, the aurora had already faded.
However, the arc still photographed well and provided a great backdrop to these rural scenes. The rising Moon, then 3 days past full, lit the foreground. In the lead image, lights from combines and trucks working the field behind the bins are at left.
The image above was from later in the night, just down the road at a favourite and photogenic grand old barn.
Note the Big Dipper above the barn. A waning and rising Moon like this is great for providing warm illumination.
The time around equinox is usually good for auroras, as the interplanetary and terrestrial magnetic fields line up better to let in the electrons from the Sun. So perhaps we’ll see more Lights, with the Moon now gradually departing the evening sky.
The aurora has been lighting up our skies a lot in recent nights, in a great sweeping arc across the northern sky.
It’s been a good week or so for Northern Lights, with several nights in a row of fine displays. These images are from one night, taken near home in southern Alberta, on September 2.
The lead image at top shows the display at its best, with the arc of curtains reflected in a nearby pond. The green curtains fade to shades of magenta as they tower into the high atmosphere, as one process of glowing oxygen giving off green light transitions to another emitting red light.
A little later the curtains had changed form, into a more homogenous arc above a set of sharper curtains below that are farthest north. People in northern Alberta or the Northwest Territories would have been seeing these curtains dancing above them.
What we are seeing is the classic curving arc of the auroral oval, the ring of light created by electrons raining down into our atmosphere in roughly an oval sweeping across the continent and centred on the magnetic pole in the Canadian Arctic.
However, at right, you can see a odd detached bit of more southerly aurora, with a dominant red colour.
This is a closeup, showing the characteristic form of these odd “isolated arcs” — usually featureless, often thin, without much motion, and often red.
Later, the arc had brightened and expanded to cross the sky. The above view is looking west from home, with the arc now displaying a mix of pink, white and green.
Here, we are looking up the isolated arc, with the impression of it being a thin sheet seen at an angle, with the bottom green component being closest and the red top being highest and farthest away.
This is the view looking southeast to the strange aurora. For a time it broke up and displayed a “picket fence” formation. And it moved!
Just what these isolated arcs are is a mystery. They have been called “proton arcs,” under the assumption they are caused by incoming protons, not electrons. But while there are such things as proton arcs and auroras, they are diffuse and invisible to the eye and camera in normal visible light. So these features are not proton arcs.
Nevertheless, these odd arcs are not like the usual auroral curtains, and likely have a different origin. But just what is still the object of research. Images by amateur astronomers such as these can help in the study.
What a night this was – perfect skies over an iconic location in the Rockies. And an aurora to top it off!
On August 31 I took advantage of a rare clear night in the forecast and headed to Banff and Moraine Lake for a night of shooting. The goal was to shoot a time-lapse and stills of the Milky Way over the lake.
The handy planning app, The Photographer’s Ephemeris, showed me (as below) that the Milky Way and galactic centre (the large circles) would be ideally placed over the end of the lake as astronomical twilight ended at 10:30 p.m. I began the shoot at 10 p.m. as the sky still had some twilight blue in it.
I planned to shoot 600 frames for a time-lapse. From those I would extract select frames to create a still image. The result is below.
As the caption explains, the still is a composite of one exposure for the sky and 16 in succession for the ground, averaged together in a technique to smooth noise. The camera wasn’t tracking the sky, so stacking sky images isn’t feasible, as much as I might like to have the lower noise there, too. (There are programs that attempt to align and stack the moving sky but I’ve never found they work well.)
About midnight, the Valley of Ten Peaks around the lake began to light up. An aurora was getting active in the opposite direction, to the north. With 450 frames shot, I stopped the Milky Way time-lapse and turned the camera the other way. (I was lazy and hadn’t hefted a second camera and tripod up the steep hill to the viewpoint.)
The lead-image panorama is the first result, showing the sweeping arc of Northern Lights over Desolation Valley.
Still images shot, I began a time-lapse of the Lights, grabbing another 450 frames, this time using just 2-second exposures at f/1.6 for a rapid cadence time-lapse to help freeze the motion of the curtains.
The final movies and stills are in a music video here:
I ended the night with a parting shot of the Pleiades and the winter stars rising behind the Tower of Babel formation. I last photographed that scene with those same stars in the 1980s using 6×7 film.
In a summer of clouds and storms, this was a night to make up for it.
My latest music video includes images, time-lapses and real-time videos of the Northern Lights shot in February and March 2016 in Churchill.
While I’ve posted my recent images of the aurora here and at many social media sites, all the videos I shoot take more work before they are ready to unveil to the public. Videos work best when set to music.
In this case, I’m very pleased to have received permission from EverSound Music to incorporate the music of one of my favourite artists, John Adorney, in my latest music video montage. The selection is If a Rose Could Speak, from his 2013 album The Wonder Well. It features vocals by Daya.
The video incorporates still images, as well as time-lapse sequences, and real-time videos of the Northern Lights.
The all-sky time-lapses are intended to be projected in digital planetarium theatres, recreating the scene on their 360° domes.

ABOUT THE VIDEO
I shot all scenes at the Churchill Northern Studies Centre, near Churchill, Manitoba, on the shore of Hudson Bay at a latitude of 58° North. Churchill’s location places it under the usual location of the auroral oval, providing spectacular displays of Northern Lights even on nights when locations to the south are seeing nothing.
I was at the CNSC to present sets of 5-night aurora viewing programs to guests from across North America. Click the link above for more details on their programs. The 2016 aurora season is over, but we’ll have more aurora programs in January and February of next year.
I shot all images with Canon 6D and Nikon D750 DSLR cameras, usually at ISO 3200. The fish-eye all-sky sequences were with a Sigma 8mm lens on the Canon, while most of the still images and other full-frame time-lapses were with the Sigma 20mm Art lens on the Nikon. For the “rapid-cadence” time-lapses I used 1- to 2-second exposures at an interval of one second.
The real-time video clips were with the Nikon – set to ISO 25600 – and the Sigma wide open at f/1.4. While these clips are prone to digital noise, they do record the fast movement and subtle colour of the aurora much as the eye saw it. See my earlier music video with real-time clips shot February 12 for more examples of these.
The all-sky sequences were processed through LRTimelapse v4 software, to handle the huge range in brightness of the Lights. Real-time video clips were processed in Photoshop with the Camera Raw filter.
Temperatures ranged from a bitter -35° C to just (!) -15° C on most nights.
I kept the long-duration, all-sky, time-lapse camera going by placing it in a Camera Parka (www.atfrostedlens.com) and inserting disposable hand warmer packs inside the insulated parka. It worked very well, making it possible to shoot for up to 3 hours. Without it, the battery died after an hour.
It was a night to remember, when the sky exploded with a jaw-dropping display of Northern Lights.
Warnings went out around the world and the aurora meters were hitting high numbers. By sunset we were charged up with high expectations of seeing the aurora in high gear dancing in the twilight. We were not disappointed.
From our location at the Churchill Northern Studies Centre near Churchill, Manitoba (latitude 58° North), we see aurora almost every clear night, even when indicators are low.
But this night, the Index was reading 7 on the scale of 0 to 9. I was afraid, after all the effort to come north to see the Lights, the Lights would abandon us and head south. Not so!
The night did start with the Lights in the south, as shown in the panorama image at top. It takes in a full 360°, with the aurora arcing from east to west across the southern sky in Orion. The north over the Centre is clear.
But the curtains soon moved back north and engulfed most of our sky for most of the rest of the night.
Participants in our aurora tour group took their aurora “selfies,” and just looked up in awe at one of nature’s great sky shows. When the last of the group turned in at 2:30 a.m. the Lights were still going.
What follows is a selection — just a few! — of the still shots I took. I also shot time-lapse sequences and real-time videos. All those will take more editing to turn them into a music video, still to come.
My 10-minute video captures the Northern Lights in real-time video – no time-lapses here!
I hadn’t tried this before but the display of February 12, 2016 from Churchill, Manitoba was so active it was worth trying to shoot it with actual video, not time-lapse still frames.
I used very high ISO speeds resulting in very noisy frames. But I think the motion and colours of the curtains as they ripple and swirl more than overpower the technical limitations. And there’s live commentary!
Select HD and Enter Full Screen for the best quality.
Scenes have been edited for length, and I did not use all the scenes I shot in the final edit. So the scenes you see in the 10-minute video actually took place over about 20 minutes. But each scene is real-time. They show the incredibly rapid motion and fine structure in the auroral curtains, detail blurred in long multi-second exposures.
I used a Nikon D750 camera at ISO speeds from 12,800 to 51,200. While it is certainly very capable of shooting low-light video, the D750 is not optimized for it. A Sony a7s, with its larger pixels and lower noise, would have been a better camera. Next time!
The lens, however, was key. I used the new Sigma 20mm Art lens which, at f/1.4, is the fastest lens in its focal length class. And optical quality, even wide open, is superb.
The temperature was about -30 degrees C, with a windchill factor of about -45 C. It was cold! But no one in the aurora tour group of 22 people I was instructing was complaining. Everyone was outside, bundled up, and enjoying the show.
It was what they had traveled north to see, to fulfill a life-long desire to stand under the Northern Lights. Everyone could well and truly check seeing the aurora off their personal bucket lists this night.

From Churchill, Manitoba the Northern Lights dance almost every night over the boreal forest.
This year, as in the last two years, I have traveled to the shores of a frozen Hudson Bay and to the town of Churchill, Manitoba to view and photograph the aurora borealis.
I’m instructing two tour groups at the Churchill Northern Studies Centre, one this week and one last week, in the science and sagas of the aurora and on how to shoot the Lights. The participants in the groups are fabulous, keenly interested and unfazed by the cold and wind.
From Churchill’s latitude of 58° N, we are under the main auroral oval almost every night. Even on nights with low official activity levels, as they were on all the nights I shot these images, we still get sky-filling displays.
Here’s a selection of still images from the last week of shooting, with clear skies on all but a couple of nights. There’s still room in our March sessions!
The Northern Lights dance over the badlands of Dinosaur Provincial Park, a World Heritage Site.
Aurora alerts called for a fine display on Friday, September 11. Forewarned, I headed to one of my favourite shooting spots at Dinosaur Provincial Park, and aimed three cameras at the sky. It didn’t take long before the lights appeared, right on cue.
The display started out with lots of promise, but did fade after 12:30 a.m., just when it was supposed to be peaking in intensity. I let the cameras run for a while but eventually stopped the shutters and packed it in…
…But not before I captured this odd bit of aurora in the east, shown below, that appeared as an isolated and stationary band pulsing up and down in brightness, but with little movement.
I’ve seen these before and have never heard a good explanation of what process creates such an effect, with a patch of sky appearing to “turn on” and off.
You can see the effect at the end of the time-lapse compilation, linked below from Vimeo.
As usual, please enlarge to full-screen and watch in HD for the best quality.
Unfortunately, a patrolling park official checking on things, spoiled some frames with her truck’s headlights. It’s one of the hazards of time-lapse imaging.
As a final image, here are all the fish-eye lens frames stacked into one image, to create a single star trail showing the sky rotating about the celestial pole.
It’s been a good week for auroras, with a promise of more to come perhaps, as we approach equinox, traditionally a good time for magnetic field lines to align, funnelling solar storm particles into our magnetosphere.
The summer Milky Way shines over the Milk River and the sandstone formations of Writing-on-Stone Provincial Park.
Earlier this week I spent two nights shooting at a favourite site in southern Alberta, near the U.S. border. Here, the Milk River winds through a small canyon and coulees lined with eroded sandstone formations called hoodoos. Carved on those hoodoos are ancient graffiti – petroglyphs dating back hundreds of years recording life on the plains. Thus the name: Writing-on-Stone.
It’s a beautiful place, especially so at night. I was there to shoot video scenes for an upcoming “How to Photograph the Milky Way” tutorial. And to collect images for the tutorial.
Above is a shot that is one frame from a time-lapse sequence, one that captures a meteor and the Milky Way over the Milk River, with the Sweetgrass Hills of Montana in the distance.
This image is from a set of exposures I took with the camera and ultra-wide 15mm lens tracking the turning sky, to prevent the stars from trailing in long exposures. A set of images with the tracker motor turned off supplied the sharp ground.
It shows the sweep of the summer Milky Way, with some clouds and forest fire smoke intruding to the south.
In both images the ground is green because, in part, it is being lit by an aurora display going on behind the camera to the north.
Here’s the view looking east, with a green aurora fringed with red lighting the northern sky.
The display on the night of July 22/23 formed a classic arc across the north. This was my panoramic view of the vast auroral oval that was wrapping around the planet at far northern latitudes. Here, I was at 49° north, almost on the Canada-U.S. border, and well south of the main oval.
In all, it was a magical two nights at a scenic and sacred site.
On June 22 I shot the great all-sky aurora with three cameras all shooting time-lapse frames. Here’s the result!
The rapidly moving and astonishing patterns of the aurora are ideal for time-lapse photography. Except for a total eclipse of the Sun, nothing else in the sky changes with such dramatic and jaw-dropping intensity.
For the June 22 outbreak of Northern Lights across the sky, I shot some 2,200 frames, and assembled them into the time-lapse compilation here.
One sequence records the entire sky and the complete development of the display, from when it first appeared in twilight about 11:15 p.m., to when it faded into a diffuse glow across the sky by 1:15 a.m. I shot that sequence with an 8mm fish-eye lens, to capture a scene suitable for projection in a digital planetarium theatre.
I shot the other sequences with 15mm and 24mm lenses. All total, the 3-minute movie comes from about 50 gigabytes of images.
Aurora watchers were on alert! Look up after sunset on June 22 and the sky should be alive with dancing lights.
And the predictions were right.
I headed out to a nearby lake in preparation for seeing and shooting the show. And as soon as the sky got dark enough the Lights were there, despite the bright solstice twilight.
The display reached up to the zenith, as seen in my fish-eye images, like the one below. I shot with three cameras, all shooting time-lapses, with the fish-eye camera recording the scene suitable for projection in a digital planetarium.
However, it was apparent we here in western Canada were seeing the end of the display that had been going on for hours during an intense geomagnetic storm. The aurora was most intense early in the evening, with a minor outburst about 11:30 to 11:45 pm MDT.
The aurora then subsided in structure and turned into a more chaotic pulsating display, typical of the end of a sub-storm.
However, an attraction of this display was its juxtaposition over another storm, an earthly one, flashing lightning to the northwest of me.
By 1 a.m. MDT the display, while still widespread over a large area of the northern sky, had turned into a diffuse glow.
But 60 gigabytes of images later, I headed home. The time-lapse compilation will come later!
The summer solstice sky was filled with twilight glows, planets, and dancing Northern Lights.
What a magical night this was. The evening started with the beautiful sight of the waxing crescent Moon lined up to the left of the star Regulus, and the planets Jupiter and Venus (the brightest of the trio), all set in the late evening twilight.
They are all reflected in the calm waters of a prairie lake.
I shot the above photo about 11 p.m., as late a twilight as we’ll get. From here on, after solstice, the Sun sets sooner and the sky darkens earlier.
Later, about 12:30 a.m., as predicted by aurora apps and alert services, a display of Northern Lights appeared on cue to the north. It was never very bright to the eye, but the camera nicely picks up the wonderful colours of a solstice aurora.
At this time of year the tall curtains reaching up into space catch the sunlight, with blue tints adding to the usual reds fringing the curtain tops, creating subtle shades of magenta and purple.
The display made for a photogenic subject reflected in the lake waters.
The northern lights returned to our prairie sky in a colourful display near solstice.
Last night, Sunday, June 7, I headed out to a nearby abandoned farmyard to shoot the planets setting into the western twilight. But as the sky darkened the faint arc of an aurora appeared to the northeast, promising a fine show after midnight.
Sure enough, as the sky got dark, which doesn’t happen until very late now at 50° north in mid-June, the aurora began to dance.
The top image is a frame from the display at its best. It is one of 400 frames I shot for a time-lapse sequence.
This image is from the start of the sequence, just as the aurora was beginning to get good, with curtains of green laced with tints of magenta and purple. At this time of year the tops of the curtains often look blue, as they scatter direct sunlight streaming over the pole.
However, the colours were not visible to the unaided eye — only the camera brought out the colours, as this display never got intensely bright to the eye.
Toward the end of the sequence the display began to spread out, becoming patchy and less colourful, a typical behaviour after a substorm outburst.
More activity may be in store this week. So keep looking up! And check Spaceweather.com for alerts.
A strange red arc of aurora moved slowly across the sky on May 10.
All indicators looked favourable early in the evening on May 10 for a good auroral display later that night, and sure enough we got one. But it was an unusual display.
From my site in southern Alberta, the northern sky did have a diffuse glow of “normal” green aurora that never did take much form or structure.
But overhead the aurora took the form of an arc across the sky, starting as an isolated ray in the southeast initially, then reaching up to arch across the sky with what looked to the eye like a colourless band.
But the camera showed it as a red arc, with just a fringe of green curtains appearing for a few minutes.

The time-lapse movie shows the sequence, over about 90 minutes, with 170 frames playing back at 12 frames per second. You can see the red arc develop, then become more narrow, then exhibit a few green curtains. Then it fades away.
Large-scale pulses also brighten the whole sky momentarily.
The other images are individual frames taken during the evening, showing snapshots of the red arc development, as it became more narrow in structure and gained green curtain-like fringes.
Presumably the red structure was very high in the atmosphere while the green curtains attached to it that did appear hung down from the high-altitude red arc.
I shot all images with an 8mm fish-eye lens to capture most of the sky. The camera is looking north toward Polaris, with the Big Dipper almost directly overhead near the centre of the frames.
The main image at top is a star-trail stack of 80 frames showing the sky’s circumpolar motion around Polaris and the aurora blurred and blended over 45 minutes of motion. I stacked the frames with the Advanced Stacker Actions from StarCircleAcademy.com
The aurora dances behind a pioneer homestead on the Alberta prairies.
After a stay of five months in New Mexico I arrived back in Alberta earlier this week, and was greeted tonight, April 15, with a display of Northern Lights. They’ve been very active in the last month, but I’ve seen nothing of them from where I was in New Mexico.
But here in southern Alberta, I just walk out onto my back deck and there they are! An email alert prompted me to have a look, after predictions earlier in the day called for little activity tonight. But indicators picked up nicely late in the evening.
I headed to an abandoned pioneer homestead near my acreage. A photogenic foreground always adds to the scene.
A little further down the road is a prairie pond, ruffled a little by wind tonight, blurring the reflection I was hoping to capture.
It’s nice to be back under the Northern Lights. Bring them on!
My new 3-minute music video compiles still and time-lapse imagery of the aurora I shot in February 2015 from Churchill, Manitoba.
Churchill’s location at 58° North on the shore of Hudson Bay puts it directly under the main auroral oval, the zone of greatest auroral activity. Over the 9 nights, 2 were cloudy, with a roaring blizzard.
But on the 8 clear nights we saw aurora every night. I shot time-lapses on 6 of those nights, shooting about 3,500 frames, most of which appear in the final cut of this movie.
Despite the amazing displays we saw, on no night was the auroral activity index (on a scale of 0 to 9) higher than 2 or 3. These were all “normal” quiet nights for auroras in Churchill. Anyone farther south would have seen little in their sky on most of these nights.
I shot many of the time-lapses with an 8mm spherical fish-eye lens, to create sequences suitable for projection in digital planetarium domes. One other time-lapse sequence (the last in this movie) I shot with a 15mm full-frame fish-eye. Even it is not wide enough to take in the entire display when the Lights fill the sky.
Exposures were typically 10 to 15 seconds at f/3.5 and ISO 1600 to 4000, all with the Canon 6D. I powered it from its lone internal battery. Amazingly, despite temperatures that were considered extreme even for Churchill (often -32° C at night) the batteries lasted 90 to 150 minutes allowing me to take lots of frames with no battery change or perhaps just one battery change. Churchill is very dry and only on one night did I have an issue with the lens frosting up.
Music is by Dan Phillipson, his composition “Into the Unknown,” purchased for royalty-free use through Triple Scoop Music. I edited the movie in Apple Aperture, with a title sequence created in Photoshop. Processing of the original images was with Adobe Camera Raw, Photoshop, and LRTimelapse, with assembly of movie frames done with Sequence for MacOS.

Last night the sky exploded with waves of green and pink as the Northern Lights danced in the bitter cold.
With blizzard conditions forecast for the next two days, last night might have been our last for viewing the aurora from Churchill. But if so, we ended on a high note.
The aurora appeared on schedule again at about 9 to 9:30 p.m., following my evening lecture, as it has done every clear night for the last couple of weeks. It began as a sweeping arc to the north, as above, then moved south to encompass the entire sky.
About 11 p.m. the sky burst open with waves of green arcs, but with generous tints of red and magenta that the camera picks up easily. To the eye, the reds are barely visible unless the aurora gets very bright.
Despite the bitterly cold temperatures of -34° C with a -50° wind chill, everyone in the tour group braved the night to take in the sight. And many managed to work their cameras and tripods, no small feat under such conditions, to get great shots.
The groups this week and last saw aurora every clear night, with clear nights on at least 3 out of the 5 nights of each course. Not a bad take, fulfilling everyone’s “bucket list” dream of standing under the aurora borealis.
It was a bitterly cold night for watching the dancing Northern Lights.
When Environment Canada issues Extreme Cold warnings for Churchill, you know its cold! With temperatures at -32° C and with high winds last night, the wind chill equivalent was -50° C.
But that didn’t stop us from watching the Lights!
I nicely finished my evening lecture at 9 pm when the Lights appeared on cue. They were faint at first, but then brightened nicely by 10 pm. The show was over by midnight, a well-timed and convenient display.
The 22 participants in this week’s course all bundled up and headed out, onto the second floor viewing deck and out onto the ground for views and photos of the aurora.
This was not a brilliant display – the official activity level was still reading only 1 or 2 on scale of 0 to 9. But it provided us with some beautiful curtains and lovely colours. The hazy appearance is from high clouds and local blowing snow.
The views from the Deck overlooking the boreal forest make for some nice photo opportunities, from a spot largely out of the constant westerly winds.
We have three more nights here, though snow is forecast for the last two. Tonight may be our last night to enjoy the Northern Lights. But all are happy with what they have seen and shot so far.
The Northern Lights have performed beautifully the last few nights, presenting curtains of light dancing across the sky.
Two nights ago in Churchill, Manitoba we were treated to a “storm level” show of aurora, with the Lights all across the sky in green curtains waving and curling before our eyes.
The curtains tower several hundred kilometres up into the atmosphere, from the lower edge at about 80 km up (still high above the stratosphere) to the curtain tops at about 400 km altitude at the edge of space.
The camera picks up the colours far better than the eye can, recording not only the predominant green hues but also shades of pink, magenta and red.
The magentas and reds come from the sections of the curtains at the highest altitudes, from the top of the auroral curtains. Here, where the atmosphere is a near vacuum, sparse oxygen atoms can glow with a red emission line.
However, there must be a blue component as well, leading to the magenta or pink tones, as in my photos here. Nitrogen can glow in blues and purples and might be contributing to the colours.
The top two photos are from Tuesday night, Feb 17, when storm levels of 5 were in effect worldwide.
Lower down, at about 100 km altitude, the air is denser and oxygen glows with a brighter green hue, which the eye can detect more easily.
The photo above from last night, with an activity level of just 2, also shows most of the sky covered with a faint emission, with a patchy appearance, with dark “holes” also moving and flowing in the time-lapse movies I shot.
Closer to the horizon, and far to the north, the aurora brightens into the more characteristic green snaking curtains.
This image from three nights ago shows an usually coloured aurora at the start of the night, glowing mostly a deeper red and orange.
The green was still off in the distance far to the east. It arrived a few minutes later as green curtains swept in over us.
But the initial red was from low-energy electrons lighting up just high-altitude oxygen. Only when the higher energy particles arrived did the sky light up green.
I shot all these images with an 8mm fish-eye lens as frames in time-lapse sequences intended for use projected in digital planetarium domes, where the 360° “all-sky” scene would be recreated on the dome as it was in real life.
If you are with a planetarium, contact me if you’d like to get aurora clips.
Our second group of aurora tourists has arrived today at the Churchill Northern Studies Centre, and the weather is warming to a high of -20° C. Balmy!
We’re hoping for more fine displays, though the space weather forecast calls for a quiet magnetic field in the next few days.
Beautiful curtains of light draped across the sky despite the blizzard blowing below.
Last night, February 16, was the last night for aurora viewing for the first aurora tour group hosted by the Churchill Northern Studies Centre.
Despite predictions calling for an active display, we had given up hope of seeing anything, as a blizzard had been raging all day and into the evening. But about 10 pm I knocked on doors down the hall — get up! The Lights are out!
Against all odds, skies cleared enough to reveal a wonderful all-sky display of Northern Lights, with multiple curtains of light snaking over the sky.
The view above overlooks the now derelict launch buildings of the abandoned Churchill Rocket Range, in use from the late 1950s until the 1980s. Some 3500 rockets were fired from here in its heyday, shot into the active auroras that occur here almost nightly under the auroral oval.
This view overlooks the boreal forest on the frozen shore of Hudson Bay, and shows the multiple curtains that twisted and turned across the sky.
Tonight’s display was marked by fringes of magenta, rather than the deeper reds we observed 2 nights ago.
Winds were howling and snow was blowing, but from the shelter of the Centre’s second floor observing deck we could view the display in windless comfort, despite the -30° C temperatures.
The group was delighted at having this bonus viewing night. Now the concern is whether the blizzard will abate enough to allow flights in and out of Churchill Airport. The group might get another night under the Lights!
The Northern Lights dance overhead each night from Churchill, Manitoba.
If you really want to see the Northern Lights, don’t wait for them to come to you. Instead, you go to them.
For the second year in a row I’ve been able to participate as an instructor during week-long aurora courses and tours at the Churchill Northern Studies Centre on the shore of Hudson Bay. The site is at 58° latitude, far enough north to place us directly under the main auroral oval, the prime location for viewing the Northern Lights.
If it’s clear, a view of dancing arcs and curtains of aurora is almost guaranteed. Two nights ago we had a marvellous display, despite official indicators of aurora strength and geomagnetic activity all reading low or even zero.
Still, the Lights came out and danced across the sky.
The top photo is selfie of me standing the display in a 360° all-sky image shot for use in a planetarium. The research centre building is at left. The view is generally looking north.
This view is from the second floor deck of the centre, usually a bit more sheltered from the wind. It allows a good view to the north and east, where displays typically start, as they did this night. Feb. 13.
As the display developed the curtain rose up into the sky to arc from east to west across heavens.
This image, also a 360° fish-eye image taken with an 8mm lens, shows the display at its best, with rippling curtains hanging overhead. It’s part of a time-lapse sequence.
The next night, February 14, was marked by fainter but an unusually red aurora, appropriate for Valentine’s Day perhaps. Or the 50th anniversary of our red and white Canadian flag.
The sky was a little hazier, but the aurora shone through, initially only with a red and orange tint, colours we could just see with the unaided eye – the long exposures of the camera really bring out the colours the eye can only just perceive when the aurora is dim.
The green curtains, seen here in the distance, did arrive a few minutes later, lighting up the curtains in the more usual green colour, with just upper fringes of red.
It seems the red is from low-energy electrons exciting oxygen only in the upper atmosphere. Only later did the more energetic electrons arrive to excite the green oxygen transition that occurs at lower altitudes.
With luck, I’ll have more nights to stand under the auroral oval and look up in wonder at the Northern Lights.
The sky events listed are for North America. While most will be visible around the world the timing may be off for other locations. Many thanks for visiting and following my blog this past year. I wish everyone a happy and celestial 2015.
The sky lights up in greens and reds from aurora and airglow.
This has been a good week for aurora watching. Friday night the Northern Lights danced again, this time in a sky already filled with a more subtle phenomenon, airglow.
Airglow adds its own bands of reds and greens across the sky, seen here as arcs from left (west) to centre (north) and into the east. Airglow is light from fluorescing air molecules releasing energy absorbed from the Sun by day.
The aurora adds the brighter green curtains across the north with vertical beams of yellow and red shooting up.
A weird structure which I assume is from the aurora is the sharp-edged yellow band at left in the west. It lasted no more than 2 or 3 minutes, enough to record in three frames of this 7-segment 180° panorama taken near home at an array of grain bins, now filled from the harvest.
To the west and east urban light pollution adds glows of yellow to the horizon.
The autumn constellations rise into a colourful sky at Dinosaur Provincial Park, Alberta.
Last night the sky started out beautifully clear but as it got darker it was apparent even to the eye that the sky wasn’t really dark, despite the lack of any Moon.
The camera captured the culprit – extensive green airglow, to the east at right. A faint aurora also kicked up to the north, at left, adding a red glow. Light pollution from gas plants nearby and from Brooks 50 km away added yellow to the sky scattered off haze and incoming cloud.
The sky colours added to the scene of the autumn constellations of Cassiopeia, Andromeda, Perseus and Pegasus rising in the east. The Andromeda Galaxy is at centre. The Pleiades is (are?) just rising over the hill.
This is a composite of five stacked and tracked exposures for the sky (with the camera on the Star Adventurer tracking mount) and four stacked but untracked exposures I took at the end of the sequence for the sharp ground (I just turned the tracker motor off for these).
The sky presents a panoramic show from Pyramid Island in Jasper National Park.
What a wonderful place to watch the stars. Last night I walked out to Pyramid Island in Jasper, via the historic boardwalk built in the 1930s. The site provides a panorama view around the lake and sky.
To the left is the “mainland.” Just left of centre the waxing gibbous Moon is setting over Pyramid Lake.
To the right of centre, the boardwalk leads out the small island, with Pyramid Mountain behind it.
To the right of the frame, a faint aurora glows to the northeast over the still waters of the lake.
This is a 360° panorama shot with the 15mm full-frame fish-eye lens in portrait orientation, with the segments stitched with PTGui software.
After shooting some panoramas I walked to the end of the island and shot this view looking north and northwest to Pyramid Mountain. The Big Dipper is to the right of the peak, and the aurora lights up the northern horizon at right.
As I shot these images, the night was absolutely quiet. Until the wolves began to howl at the north end of the lake, in mournful howls that echoed across the waters.
It was one of the most spine-chilling moments I’ve experienced in many years of shooting landscapes at night.
The northern lights dance, and light the pioneer homes at the old Larson Ranch in Grasslands National Park.
What a night this was! I arrived at the Larson Ranch site in the Frenchman River valley to shoot some Milky Way panoramas, when, right on cue, the aurora broke loose.
Some aurora had been there since nightfall as a diffuse arc, but about 11 p.m. local time (Central Standard Time in Saskatchewan) the curtains began to dance and pulse with activity as a sub-storm hit, raining solar particles onto our atmosphere from down the magnetic tail of the Earth.
The aurora glow lit the old pioneer buildings of the Larson Ranch, one of the stops on the scenic backroad drive through the Park.
The Larsons ran their ranch by the Frenchman, or Whitemud River, from the 1920s until 1985 when they sold their ranch to the National Park system, forming the first land for the new Grasslands National Park.
The house at left is the original home of cowboy author Will James, who lived here for a time working on ranches in the valley before moving to the United States. He was from Quebec, where he was Ernest Dufault.
I shot this 360° panorama using a 15mm lens, shooting 8 segments at 45° spacings, each a 1-minute exposure at ISO 2500 and f/3.2 with the Canon 6D. I used PTGui software to stitch the segments into a equi-rectangular projection pan.
The Milky Way and the Northern Lights arch across the sky in the Frenchman River valley of Grasslands National Park.
This 360° panorama takes in two arches of light:
• The Milky Way rising out of the northeast at left and stretching across the sky overhead at top and down into the southwest at right of centre.
• And the Northern Lights, as an arc of green and red across the northern horizon. They got brighter and higher later this night, August 26/27, as my previous post shows.
Bands of green airglow also stretch across the sky from east to west.
I shot this last night from the Frenchman River coulee, a wide valley cut at the end of the Ice Age by glacial run off, and occupied today by the meandering Frenchman River. It winds through the heart of Grasslands National Park and makes its way to the Missouri River to drain into the Gulf of Mexico, one of only a handful of rivers in Canada to do so.
The river and wide pasture land made this a choice place for a ranch. For decades this was home to the 76 Ranch, one of the largest in Canada. At right is its old wood corral, in front of the Milky Way and its “Dark Horse” structure in the dark lanes of the Milky Way. Appropriate I thought.
The only lights visible are from spotlights from researches conducting studies of the nocturnal black-footed ferret. Otherwise, the site was as dark as you’ll find it in southern Canada.
I assembled this panorama using PTGui software, from 8 segments shot with a 14mm lens in portrait orientation, all untracked 80-second exposures at ISO 4000 and f/2.8.
The Northern Lights dance over the prairie landscape of Grasslands National Park.
The aurora warnings were out for last night but I hadn’t expected to see much. But about 10:30 pm a faint arc appeared to the northeast. The display brightened about local midnight (Central Standard Time here in Saskatchewan) and became fairly active for a time.
The main arc increased in intensity and moved with fine structure and detail. The eye could see some faint, colourless curtains extending upward but the camera picks them up as red, typical of auroral curtains reaching into the top of the atmosphere.
I shot these from the Frenchman River valley, a wide coulee formed by glacial rivers and now the heart of the West Block of Grasslands National Park.
It was a beautifully dark site except for flashes of spotlights now and then (not seen in the photos here) from naturalists doing census studies of the nocturnal and endangered black-footed ferret recently re-introduced to the Park. Ironically, their lights spoiled the otherwise pristine and pitch-black night in this dark sky preserve.
What a fabulous night this was! Forewarned about an impending solar storm I headed to the site of a rustic barn near home to shoot the Northern Lights.
The night started with cloud but upon looking out after midnight (it pays never to go to bed too early!) the skies were clear. Checking Spaceweather.com showed an active auroral oval lit up red and Storm in Progress warnings!
That was all the cue I needed to pack up the gear and head over to the old barn site where I have been shooting time-lapses all this week.
The aurora remained quiet and diffuse for the first hour and a half, but then about 2 a.m., the substorm hit. Within seconds the curtains began to light up with well-defined rays and beams shooting to the zenith. And they danced.
The notable feature of this display, as with one in May 2013, was the blue and purple colour of the tops of the curtains. I think this is partly due to sunlight illuminating the tops of the curtains, possible at this time of year when the upper atmosphere is perpetually lit by the midnight Sun.
From the start I shot with two cameras taking time-lapses (the main still image at top is a frame from one of the movies). Then toward the end of the night I switched to just shooting still images framed to suit the curtains towering up to the zenith.
As above, I also shot a “selfie” of me shooting the vertical image in the middle of the set.
But below is the result of a night of shooting time-lapse movies and stills, in a montage set to music. The link takes you to my Vimeo site. Do turn on HD mode.
Here’s a time-lapse of the strange glow of light that moved across the northern sky on the night of the Camelopardalid meteor shower.
What I thought was an odd curtain of slow-moving, colourless aurora — and I’ve seen those before — has many people who also saw it suspecting it was a glow from a fuel dump from an orbiting satellite. Perhaps.
This short time-lapse of 22 frames covers about 22 minutes starting at 11:59 pm MDT on May 23 (as logged by the camera’s GPS). Each frame is a 60-second exposure taken at 2 second intervals. I’m playing them back at one frame per second.
The camera was on a tracking platform to follow the stars — thus the ground slowly rotates. This was one of the cameras I had operating the night of May 23-24 to capture meteors from the Camelopardalid meteor shower. The shower was a dud, but …
The most interesting thing my cameras did catch was this odd glow which started large and diffuse and then became more defined as it got smaller and moved off (or so it appears) to the north, then fades away. My photos (and I have it on frames from another camera), and photos taken by other observers across North America, show a faint satellite moving along south to north parallel to the cloud’s long axis. Is this the culprit that caused the cloud? If so, it would have to be very high to be seen from a wide range of longitudes – astronomers in Manitoba and Minnesota also saw and shot it.
But any fuel dumps I’ve seen always have clouds that start small and concentrated then become large and diffuse. This did the opposite.
The Milky Way, an odd aurora, and the glow of urban light pollution lit the sky. But alas, no meteors!
On Friday afternoon, May 23 I headed 3 hours east of home toward the clearest skies in the province. The quest was for sightings of the Camelopardalid meteors, the new and much publicized meteor shower from Comet LINEAR, 209/P that had been predicted for tonight.
I had very good skies for the first couple of hours of darkness, from a viewpoint looking north over the prairies on the high rim of the Cypress Hills, Alberta. Clouds did move in about 12:30 a.m., about the time the shower was to be peaking. But up to that point I had sighted just a handful of meteors and many were likely random ones, as they didn’t seem to be streaking out of the radiant point. A few other people who had converged at the site saw other meteors to the south that might have been shower members.
Perhaps the peak came later under cover of clouds. But up to 12:30 a.m. I saw little sign of an active shower. Still, it was worth taking the chance to chase into clear skies in hopes of bagging a herd of Camelopardalids.
I shot hundreds of frames with two cameras and none picked up a Cam meteor – lots of satellites, like the streak at lower centre. And for a few minutes this strange white auroral curtain appeared, slowly drifting from east to west across the northern sky, like a searchlight, above the magenta horizon glow of low-level aurora. To the northwest glowed the lights of Medicine Hat, illuminating the clouds toxic yellow in a classic demonstration of light pollution.
The northern lights – the aurora borealis – shine above the trees of the northern forest – the boreal forest.
This was the scene on Sunday night, February 9, 2014, as the aurora intensified for a few minutes making for a photogenic backdrop to the snow-covered pine trees of the boreal forest.
The landscape looks like daylight but is actually being lit by the light of the bright waxing Moon in the south. These scenes are looking north.
I shot these images as part of my stay at the Churchill Northern Studies Centrewhere I have been presenting enrichment lectures to two groups of tourists here to see the northern lights during week-long stays. Both groups have been successful in seeing the lights on at least one to two nights of their stay, with the displays usually appearing as sky-spanning arcs overhead.
Here I took the time to take a “selfie” under the northern lights, as the curtains began to wave early in the evening.
In all, it has been a fantastic experience, to witness the lights from a site right under the active auroral oval at 58° north.
Watch waves of aurora wash over the sky rising out of the west to swirl overhead.
This was the spectacle we saw Friday night at the Churchill Northern Studies Centre, as the northern lights filled our sky. I set up my camera on the east side of the main building, out of the bitterly cold west wind. The fish-eye lens is aimed west but its view takes in most of the sky.
The bright object at lower left is the Moon.
The still image above is a frame from the 349-frame time-lapse movie below.
Each frame is a 7-second exposure at f/3.5 and ISO 1250. The interval is 1 second.
The movie covers about 45 minutes of time, compressed into 30 seconds. It shows the aurora peaking in intensity, then fading out behind the ever-present thin cloud drifting through all night.
What amazes me are the waves and loops of auroral curtains that come at us from the west (bottom behind the building) then swirl around the zenith overhead. They move off to the east and north at the top of the frame.
Even watching this in real-time the scene was astonishing. The curtains rippled so quickly, forming and reforming over the sky, you didn’t know where to look. As the image above shows, people just stood amazed.
