I’ve been visiting Churchill, Manitoba during winter aurora season since 2014. But this was my last year for standing under its fabulous Northern Lights.
From February 21 to March 4, 2025 I was at the Churchill Northern Studies Centre for my annual visit serving as an instructor to visiting aurora tourists. I’d been doing the program for ten years, with a year off in 2021 when no one visited!
But I decided this was to be my last year, as it was time to “retire” and turn over the program to a new generation of instructors.
So here I present my last look at the Churchill auroras.
A 180º panorama across the north during an all-night display of Northern Lights, from the Churchill Northern Studies Centre, in Churchill, Manitoba, on February 22, 2025. A panorama of 7 segments, each 13-second exposures with the Viltrox 16mm lens at f/2 on the Nikon Z6III at ISO 1600.
Churchill, Manitoba is on the shore of Hudson Bay at a latitude of 58º North in the sub-Arctic.
It lies under the normal location of the “auroral oval,” the ring around the North Geomagnetic Pole where there is almost always some aurora happening, even on a quiet night. Churchill is as far south as the auroral oval appears in the world when the oval is in its normal state.
By visiting a site under the oval, aurora tourists are almost guaranteed a show, provided the sky is clear.
This is a 180º panorama of the Northern Lights across the northern, eastern and southern sky on February 27, 2025 during a Kp4-level display. This is a panorama of 3 segments, each 13-second exposures at f/2.8 with the Laowa 10mm lens on the Nikon Z6III at ISO 1600.
In winter in Churchill, the cold usually brings clear skies. In a decade of conducting programs I’ve only ever had one group clouded out for all five nights of the program. That’s a far better average than locations such as Iceland.
This is a 120º panorama of the Northern Lights across the northern sky on February 26, 2025 during a Kp3-level display. This shows some fine ray structure in the curtains. This is a panorama of 2 segments, each an 8-second exposure at f/2.8 with the Laowa 10mm lens on the Nikon Z6III at ISO 1600.
While several excellent travel companies and local businesses offer aurora tours to Churchill, signing up to one offered by the Northern Studies Centre offers some major advantages.
Notably, guests stay at the Centre, some 20 kilometres outside of Churchill on the site of the old Rocket Range. That makes the site dark and free of light pollution.

And convenient. Guests sleep on site and need only dress up warm to quickly head outside when the “Lights are out!” call comes. Instructors wake up guests when the Lights don’t appear until late at night, as can often be the case. There’s no driving out to dark sites to wait for the Lights to appear.

An option is also to head up to the CNSC’s rooftop aurora dome for viewing the Lights in warm shirt-sleeve comfort.
Aurora tourists enjoy the show at the Churchill Northern Studies Centre, February 26, 2025. This was the Learning Vacations tour group in late February 2025. This is a single 8-second exposure with the Laowa 10mm lens at f/2.8 and Nikon Z6III at ISO 1600.
But most guests opt to bundle up and brave the cold for the best experience and unobstructed views of the Lights filling the sky. A convenient option is the second floor observation deck, shown above, and in an image taken from the deck, below.

This was the first night of a five-night session for aurora tourists from the Road Scholar education travel company. This is a single 4-second exposure with the Laowa 10mm lens at f/2.8 and Nikon Z6III at ISO 3200.
The program includes nightly science talks about the aurora and night sky. The daytime program includes dogsledding, snowshoeing, a tour of the old Rocket Range, and visits to sites in Churchill such as the murals and museums. It’s a very full five days of programming and learning.
A fish-eye 360° view of a dim and weak display of Northern Lights on February 24, 2025, showing a green diffuse band to the south and a dim red curtain overhead with rays to the east. This red aurora was just visible to the eye as a grey streak. A single long 30-second exposure with the TTArtisan 7.5mm fish-eye lens wide open at f/2 on the Nikon Z6III at ISO 1600.
The main attraction, the aurora, can vary from night to night. However, even when the aurora is weak, as it was this night, above, it can still put on a fine show for the camera, glowing in red colours that only long exposures reveal.

While I use high-end cameras and fast lenses, I’ve been impressed with how well today’s phone cameras can capture the Lights very simply and easily, as a guest is doing above, especially when the aurora is bright.
A band of bright green aurora appears here with some subtle red rays at right and magenta upper curtains at left, with the green glow lighting the snow green. A 10-second exposure with the Laowa 10mm lens at f/2.8 on the Nikon Z6III at ISO 1600.
When the aurora brightens, greens and sometimes pinks are visible to the eye, and not just to the camera. And the aurora exhibits rapid rippling and waving motions (check the video below).

This is looking northeast toward the direction of the midnight sector where the auroras usually brighten from. This is a single 8-second exposure with the Laowa 10mm lens at f/2.8 and Nikon Z6III at ISO 1600.
The finest sight is when the aurora curtains converge overhead at the zenith for a “coronal outburst.” The effect can be fleeting but the sight is unforgettable. It is one of the finest sights the sky can offer, ranking with a total eclipse of the Sun.

Orion and Sirius are at bottom centre to the south. A single 10-second exposure with the TTArtisan 7.5mm fish-eye lens at f/2 on the Nikon Z6III at ISO 1600.
Indeed, on most nights the aurora, which might begin as a low arc across the north, moves south to fill the sky with swirling and curling curtains, as below.
This is a 180º panorama of the Northern Lights across the northern sky on February 27, 2025 during a Kp4-level display. The field extends from the horizon up to well past the zenith. This is a panorama of 6 segments, each an 8-second exposure at f/2.8 with the Laowa 10mm lens on the Nikon Z6III at ISO 1600.
A gallery of my images from Churchill from this year and from past years is on my main AmazingSky.com website here.

It’s been a great ten years taking in the wonderful Northern Lights in Churchill. While this was my last year, I encourage you to visit to see the sights for yourself.
Everyone goes away with great memories, able to check the aurora off their bucket list of experiences.
The Sun peaked at “solar maximum” and gave us wonderful sky shows in 2024.
Officially, the Sun reached the peak of its roughly 11-year cycle of activity — “solar max” — in late 2024. That’s according to NASA and NOAA.
During 2024 several major solar storms erupted as a result of the Sun’s increased activity. They blew massive clouds of energetic particles — electrons and protons — away from the Sun. Some of those storm clouds swept past Earth, sparking bright auroras widely seen in both the Northern and Southern Hemispheres.

I was fortunate enough, as many were, to witness several of 2024’s great auroras, from home in Alberta, and from as far south as Arizona.
Trips north to Churchill, Manitoba, and to northern Norway also presented some fine aurora nights. But that’s normal at any time in the solar cycle from those sub-Arctic and Arctic locations.
It’s when the aurora comes to you that you get a truly memorable show. And 2024 had its share of them.

Starting the Year — February in Churchill
This was the month I made my annual trek to Churchill, Manitoba, to instruct aurora tour groups at the Churchill Northern Studies Centre. Why not join us in 2025?
An aurora selfie at the Churchill Northern Studies Centre, on February 10, with a modest Kp4-level storm underway. This is 20-seconds with the TTArtisan 11mm fisheye lens at f/2.8 on the Canon R6 at ISO 1600.
Yes, the air is cold (usually about -25° C) but the skies are often clear and aurora filled, as Churchill sits under the normal location of the auroral oval, the main zone of auroras. In fact, it is as far south in the world as the auroral oval normally resides, at a latitude of only 58º North, well south of the Arctic. If it’s clear, there’s almost always some level of Northern Lights.
This year, 2024, was no exception. Even on nights with low readings on the usual auroral indicators we got sky-filling displays that are rare down south.
This is a southerly arc of green and red Northern Lights on February 9. This is a panorama of 5 segments, each 20 seconds with the Laowa 15mm lens at f/2 on the Canon R6 at ISO 1600.
What I find in Churchill is that even with numerically weak and visually dim shows, as above, the camera often sees very red and photogenic auroras. The eye sees the colours only when the aurora brightens, which it often does (as I record below), sparking rippling green curtains (from glowing oxygen) fringed with pink (from glowing nitrogen).
I didn’t shoot time-lapses or movies this year in Churchill. Instead, the example movie above, shot using just real-time (not time-lapse) videos, is from February 2019. It is from my AmazingSky YouTube channel.
The video presents the aurora much as the eye saw it, and as it appears when it dances.
This is a 360º panorama of the all-sky aurora of February 10, from the Churchill Northern Studies Centre. This is a panorama of 9 segments, each 15 seconds with the TTArtisan 11mm lens at f/2.8 on the Canon R6 at ISO 1600.
However, I tend now to shoot mostly panoramas, as above, from this year’s visit. They can take in the full show across the sky, in high-resolution images suitable for framing!
May 10 — The Great May Display
The aurora apps were beeping this day, warning a great display was in the offing. The composite satellite image below from NOAA shows the actual extent of the aurora around the Northern Hemisphere during the great display of May 10/11 .
Note how the auroral oval is indeed an oval and how the centre is not the geographic North Pole. It is the North Geomagnetic Pole, in the High Arctic of Canada. 🇨🇦 So the oval dips down farther south over North America than it does over Europe.

The May 10 solar storm rated a top “G5” on the G1 to G5 storm scale, while the “Kp”geomagnetic disturbance index reached Kp8 on the Kp0 (nothing) to Kp9 (OMG!) scale.
I gave a talk at a local community art gallery that evening, and alerted the audience to the likelihood of fine aurora later that night. Sure enough, I got home in time to see the sky already lighting up with aurora in the twilight and behind the clouds.
This was the multi-coloured curtain to the south during the great display of May 10. This is a 10-second exposure with the Laowa 15mm lens at f/2.8 on the Canon Ra at ISO 1600.
The clouds cleared off enough to reveal one of the most colourful shows I’d seen in many years. This time there was no question about seeing reds and vivid pinks with the unaided eye. This was the type of show everyone hopes for. But it takes a Kp6 show and higher to spark it.
This was the view as the aurora suddenly brightened and converged at the zenith for a superb corona effect. This lasted no more than a minute before it dimmed and subsided again. This is a 9-second exposure with the Laowa 7.5mm circular fisheye lens at f/2 on the Canon R5 at ISO 800.
And a music video of the May 10 display incorporating time-lapse and real-time video footage is on my YouTube channel, with the clickable link below. Do enlarge to full screen.
One of the most remarkable aspects of this show was the blue auroras later in the night (shown below), created by sunlight illuminating the upper curtains and reacting with atmospheric nitrogen. The usual auroral greens and reds are from oxygen. Pinks are also from nitrogen. Blues are less common, but were in abundance this night.
This is a 360° panorama of the May 10/11 aurora exhibiting vertical blue and magenta rays across the western (left), northern (bottom), and eastern (right) sky, and an odd bright patch to the south at top. This was toward the end of the main activity this night, at about 2:30 am. This is made of 20 segments, each 13-second exposures, with the Laowa 15mm lens at f/2 on the Canon Ra at ISO 800.
Auroras around summer solstice, June 21, can be more colourful and often blue, as the Sun lights the upper atmosphere all night. I saw blue auroras again later in the summer.
July — NLCs and Classic Auroral Arcs
June and July are normally when we in western Canada get good displays of another northern mid-latitude phenomenon, noctilucent clouds (NLCs).
This shows sunlit noctilucent clouds in the northwest in the summer twilight, and as the waxing crescent Moon sets at left. This was July 9 at 11:45 pm MDT, in a panorama of 5 segments, each a 30-second exposure with the Canon RF24-105mm lens at f/4 and 58mm on the Canon R5 at ISO 400.
These are ice clouds at 80 km altitude (almost in space) that are lit by sunlight all night long. I saw only a couple of displays of NLCs this year, and it wasn’t for lack of trying and clear nights, even amid forest fire smoke. The panorama above is from home on July 9, over a yellow canola field. NLC season always coincides with peak canola colour time!
Might NLCs be suppressed by high solar activity? There’s some data that suggests they are. However, we weren’t getting many auroras either in early summer.
A 180° panorama of the surprise aurora of July 25, as there was little indication in the days before that an aurora was possible this night. This is a panorama of 6 segments, with the Viltrox 16mm lens at f/2 on the Nikon Z6III at ISO 800, each 8-second exposures.
But at the end of July the Northern Lights returned for some classic shows of arcs across my northern sky, first on July 25 (above), with a prominent sunlit blue/purple ray at left by the Big Dipper. The Kp Index reached Kp5 this night, which is enough to produce a good display from my location in southern Alberta. The Moon is rising at right.
A 180° panorama of the Kp5-level aurora on July 29, with a green arc, and magenta and red rays. This is a panorama of 8 segments, each 30-second exposures with the Viltrox 16mm at f/2 on the Nikon Z6III at ISO 800.
Then again, four nights later on July 29, an auroral arc appeared across the north, this one with reds mixing with greens to create a yellow band in the east, as well as blue and magenta tops to the green arc that follows the curve of the auroral oval.
August 1 — STEVE Appears
While June and July were quiet months, August made up for them.
Of all the auroras this year, only this one, on August 1, produced a showing of STEVE, at least as best I saw in 2024. He can be elusive and easily missed!
This is a capture of a faint appearance of a STEVE-like arc during the Kp5 aurora of July31/Aug 1. This was at 12:10 a.m. MDT, so on Aug 1. The camera recorded the pinkish rays at right which are likely STEVE arcs below a more diffuse and fainter red band which may be a SAR, a Stable Auroral Red arc.
STEVE is the odd arc, often white or mauve, that appears southward of the main aurora (from here in the Northern Hemisphere), typically after a show has peaked, then subsided and retreated back north, as it did above.
STEVE stands for Strong Thermal Emission Velocity Enhancement, as it is caused by horizontally flowing hot gas, and so is not, by definition, a true aurora created by energetic particles raining vertically down magnetic field lines.
For a classic showing of STEVE see my video, above, from August 2022. High-resolution 4K video I shot this night formed the basis for a scientific research paper, as it revealed structures in STEVE no one had seen before.
This is a capture of a brief appearance of a STEVE arc in the west during the Kp5 aurora of July31/Aug 1. This was at 1:10 a.m. MDT, so on Aug 1. The mauve STEVE arc was visible for about 15 minutes before it gradually faded. The green picket fence fingers, which were visible to the eye but colourless, appeared only a minute or so before this image and were gone no more than 2 mnutes later.
STEVEs are often accompanied by green “picket fence fingers” hanging down from the mauve arc. These fingers are more akin to normal auroras, but are created by particles from the STEVE band raining down local magnetic field lines. They do not come from far out in space as they do in a normal aurora!
August 4 — A Coronal Outburst
On the night of August 3/4 I was able to join a photo tour run by local photographer Neil Zeller, to shoot Milky Way nightscapes. Escaping clouds, we ended up at a scenic spot south of Medicine Hat, Alberta, called Red Rock Coulee.
A 180° panorama of a Kp5-level aurora on a partly cloudy night, August 3/4. This was looking to the northeast at 3:00 am from a side road off the Trans-Canada Highway in southern Alberta just east of Brooks.
On the way home, the aurora began to let loose behind the clouds. We stopped once off the highway as the aurora brightened in an arc across the northeast, above.
A bright auroral curtain sweeps from the zenith down the western sky, as the sky brightens with the blue of a dawn twilight. This was the morning of August 4, with a Kp5 to 6 level aurora underway. The location was just off Highway 1 between Brooks and Bassano, Alberta. This is a single 13-second exposure with the Viltrox 16mm lens at f/2 on the Nikon Z6III at ISO 400.
We stopped again later, now at 4 am, and marvelled as the curtains converged at the zenith in the finest manifestation an aurora can produce, a swirling zenith “corona.”
A music video from August 4, using just a single real-time video, not a time-lapse, is above. It shows almost the full but brief appearance of the corona, just as the eye saw it looking straight up!
My plan was to shoot the annual Perseid meteor shower that was to peak on Sunday, August 11, from the same spot I shot it in 2016.
A 270° panorama of the aurora in the evening twilight on August 11, from the 70 Mile Butte trailhead in Grasslands National Park, West Block near Val Marie, Saskatchewan. This is a panorama of 11 segments, each 15 seconds with the Laowa 15mm lens at f/2.8 on the Canon R5 at ISO 800.
The aurora had other plans. Again, as it did on May 10, the sky was lighting up with colours as it darkened in the evening twilight, above.
This is a 360° all-sky panorama of the Kp6 to 7-level aurora on August 11, from Grasslands National Park. This is a panorama of 12 segments, each 4 seconds with the Laowa 15mm lens at f/2 on the Canon R5 at ISO 4000.
The aurora expanded to fill the sky, and with odd fragmented bits, shown above. My trio of cameras set up for the meteor shower got repurposed into taking aurora time-lapses, stills, and panoramas. And selfies! — the title slide for this blog was from this memorable night at Grasslands.
The aurora was bright enough during this substorm outburst at 12:15 am that the red and green colours could be seen with the eye, though they were subtle. This is a 2-second exposure with the Laowa 15mm lens at f/2 on the Canon R5 at ISO 3200.
A notable moment was at midnight when, even to the eye, the sky to the east suddenly turned red, and a wave of crimson aurora quickly swept in. The reds from oxygen mix with the more usual auroral greens, also from oxygen, to create areas of yellow in the sky.
This was also peak night for the 2024 Perseid meteor shower. One bright Perseid meteor shoots down the Milky Way in Cygnus at top, amid the converging rays of the aurora at the magnetic zenith. This is with the Laowa 10mm lens at f/2.8 on the Nikon Z6III at ISO 6400 for 2 seconds.
A few still frames in the time-lapses did manage to catch a Perseid meteor or two, as above, embedded in the vivid curtains of light. But the meteors were upstaged by the Northern Lights this night.
A music video of this show is above, also on my YouTube channel (it’s been a busy year!). Using only time-lapses, it captures the sudden arrival of the red sub-storm, sped up to be sure, but it seemed that quick!
August 30 — From Onset to Recovery
This night I was hoping to shoot deep-sky objects with telescopes I was testing at home. Again, the aurora had other ideas.
This view is looking north, but the fisheye lens is taking in much of the sky. The August 30 show was somewhat unexpected, though there were last-hour warnings a sky-covering display might be possible. This is a single 4-second exposure with the TTArtisan 7.5mm fisheye lens at f/2 on the Nikon Z6III at ISO 3200.
As the movie shows, a band of Lights across the north early in the evening promised to develop. So I set up a time-lapse camera and fisheye lens to capture, for once, a complete development of an aurora, from a diffuse band, to the onset of an active sub-storm outburst which occurred, as they often do, at midnight when we are looking down Earth’s magnetic tail at the source of the aurora particles.
As the video shows, the storm then subsides and the aurora changes character. During the post-sub-storm “recovery phase,” usually when we are under the dawn sector of the auroral oval, an aurora can switch to a pulsating effect with patches of aurora flashing off and on and flaming up to the zenith. This form of aurora is caused by electrons trapped in the Van Allen radiation belts that are bouncing back and forth from pole to pole.
The music video of this show, above, uses a mix of time-lapses and real-time videos shot with the 360º 7.5mm fisheye lens. It’s a great aurora lens for capturing it all!
September 16 — A Colourful All-Sky Show
Auroras are often most frequent, active, and bright around the spring and autumn equinoxes, when the magnetic field lines of Earth and interplanetary space better connect. It’s called the Russell-McPherron Effect.
This is a 360° panorama from left (southeast) to right (northeast) and extending from the horizon to the zenith, taking in the entire sky during an outburst of a particularly colourful aurora on September 16. This is a panorama of 12 segments, each 4 seconds with the Laowa 15mm lens at f/2 on the Canon R5 at ISO 400.
September 16 (6 days before the autumnal equinox) saw another all-sky show that, for us in western Canada, rivalled May 10. As with the spring show, this aurora was notable for its great range of colours, with nitrogen pinks and magentas mixed in with shades of oxygen yellow-greens and reds.
A darker blue-green band to the south (at left above) during the peak could be aurora from incoming protons exciting hydrogen, not from the usual electrons that excite all other auroras and light up oxygen and nitrogen atoms and molecules.
Yes, there are proton auroras. Another research paper using my images from an October 2021 aurora explored the relationship between proton auroras and SAR arcs (explained below).
This is an all-sky 360° panorama from the horizon at the edges, to the zenith at centre, taking in the entire sky during an outburst of a particularly colourful aurora on September 16. This is a panorama of 12 segments, each 4 seconds with the Laowa 15mm lens at f/2 on the Canon R5 at only ISO 400.
The September 16 show started with a diffuse band which quickly exploded as a sub-storm onslaught of energetic particles arrived to light up the aurora with greater brilliance, colours, and rapid motion. The onset of a substorm can happen in literally just a minute.
Even the nearly Full Moon failed to diminish this show, seen from home under perfect skies. Luckily, the smoky season had abated.
A music video of this night’s show is also above on YouTube. Do click through to watch this and the other videos in full screen mode.
October 10 — Red Aurora from Arizona
Six months to the day after the great May 10 show, the sky erupted again with auroras seen all over the world, even from more southerly latitudes that don’t normally see Northern Lights.
A rare red aurora seen from latitude +32º N from southeast Arizona during the major Kp8-level storm of October 10. This is looking north from the Quailway Cottage near Portal, Arizona and Rodeo, New Mexico. This is a single 15-second exposure with the Canon RF15-35mm lens at 15mm and f/2.8 on the Canon R5 at ISO 1600.
I know because I was at one of those latitudes, in southern Arizona at 32° N. The aurora created the kind of show seen from areas that don’t normally get auroras — a red sky on the horizon. It is these ominous red skies that provoked Medieval fears of divine wrath and myths of armies clashing in the distant North.
Red auroras can also occur in the Southern Hemisphere (as can every other form of aurora) when the aurora australis brightens and extends farther north than normal, lighting up the southern sky red at locations that rarely see the Southern Lights.
In both cases we are seeing just the red tops of distant curtains that mostly lie hidden over the horizon, the red coming from oxygen reactions that can happen only at the rarefied altitudes of 300 to 500 km. Oxygen greens come from 100 to 300 km up.
From Arizona, I saw what many in the U.S. saw this night — a prominent glow, obviously red even to the eye, across the northern horizon. I was missing a far better show at home!
This is a 360° panorama covering the entire sky and extending up to the zenith at centre, capturing a rare SAR (Stable Auroral Red) arc across the Arizona sky in the pre-dawn hours of October 11. This is a panorama of 12 segments, each 30 seconds at f/2.8 with the Canon RF15-35mm lens on the Canon R5 at ISO 3200.
But unique to my more southerly site was this phenomenon, also widely seen across the U.S. and southern Canada.
Accompanying the “normal” aurora to the north was a diffuse red (to the camera) arc across the sky that lasted most of the night. This was a Stable Auroral Red (SAR) arc, created by thermal energy flowing horizontally in the high atmosphere some 400 km up.
SARs have been seen evolving into STEVEs, as the mechanisms seem related. Indeed, one of my images from August 1, shown above, seems to show a SAR/STEVE hybrid.
I set up a wide-angle lens and time-lapse hoping to catch such an evolution first-hand, which would have been of great interest to researchers. Alas, the SAR did not cooperate, stubbornly remaining a SAR all night.
This was the pre-dawn scene from southeastern Arizona on the morning of October 11 that frames a suite of skyglows. This is a panorama of 3 segments, each a stack of 5 x 1-minute tracked exposures with the Canon RF15-35mm lens at 15mm and f/2.8 on the Canon R5 at ISO 1600.
By dawn, with blue sunlight at work, the SAR looked magenta in the twilight, accompanied by two other sky glows:
The pyramid-shaped Zodiacal Light created by sunlight reflecting off cometary and meteoric dust in the inner solar system,
And the winter Milky Way, created by the combined light of distant stars in our section of our Galaxy.
So in one image we have atmospheric, interplanetary, and interstellar sky glows! This was truly an amazing sky, the likes of which I might never see again.
Ending the Year — November in Norway
In early November I headed to Norway to instruct my first aurora group there since 2019. The location was on board a ship, the m/s Nordkapp, a ferry in the Hurtigruten fleet that does 12-day runs along the coast, from Bergen in the south, to Kirkenes in the far north, and back again.
Passengers on board the m/s Nordkapp are watching the Northern Light show on November 9, from the coast of Norway. This is 0.4 seconds at f/1.8 with the Nikkor 20mm lens on the Nikon Z6III at ISO 3200.
We got three nights in a row of active auroras on the northbound voyage. A Kp4 to 5 storm brought the Lights farther south and overhead for us early in the voyage, something we don’t normally see in Norway until we get underneath the auroral oval, which at that longitude in the world lies above the Arctic Circle, north of 66° latitude.
A colourful aurora appears in the darkening evening twilight sky at sea along the coast of Norway on November 9. This is a single 2-second exposure with the 20mm Nikkor lens at f/1.8 on the Nikon Z6III at ISO 1600.
But on November 9, with a storm underway, the show started early, rudely interrupting our group’s cocktail hour as we all rushed up on deck. As it can do, the aurora glowing in a twilight sky took on added tints.
This is a panorama of auroral arcs across the southern sky, with prominent red content contrasting with the oxygen yellow-green bands. Taken on November 10/11 (just after midnight). This is a panorama of 7 segments, each 1.3-second exposures with the Nikkor 20mm lens at f/1.8 on the Nikon Z6III at ISO 3200.
The next night, November 10, as we sailed through the mountainous Lofoten Islands, we were treated to an aurora with lots of red content, above. No two auroras are alike!
An arc of Northern Lights points the way into the narrow Trollfjord in the Lofoten Islands of Norway, as our ship, the m/s Nordkapp enters the fjord at night by searchlight. This is a 0.5-second exposure at f/1.8 with the Nikkor 20mm lens on the Nikon Z6III at ISO 1600.
A curtain of aurora also nicely pointed the way into the short but scenic Trollfjord, a fjord the ship captains like to navigate into for a memorable side trip as we slide through the narrow canyon with seemingly inches to spare.
A music video of real-time aurora sequences shot from on deck during my November 2024 Norway cruise is above on YouTube. Note the phones held high, the way most people now shoot the aurora, and usually with very good success!
What’s Coming for 2025?
We have more to look forward to in 2025.
First, it is likely that the Sun has not peaked, but may undergo a second peak of maximum activity in 2025 or 2026. A double peak is common at many solar maxes. Just look at the graph at the opening of the blog, and the previous peaks of Cycles 23 and 24.
Plus, the most energetic solar flares and storms often occur after the peak on the downward trend of activity. So we could well see more worldwide aurora displays like we had on May 10 and October 10 in the coming two to three years. The show is far from over!

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.
Guests in the Learning Vacations program at the Churchill Northern Studies Centre view the aurora on their first night of the program for 2019 on January 31. This is looking east, with the Big Dipper at left and Orion at right.
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!
A photographer and volunteer at the Churchill Northern Studies Centre (Brian) shoots the aurora from up the Rocket Range Road at the Centre. This was Feb 8, 2019 on a brutal night with brisk winds and high wind chills. This is a single exposure with the 15mm lens and Sony a7III.
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.
One of a short series of images showing the development of an aurora display from a classic arc into a more complex pattern of concentric arcs and with loops and swirls. This was Feb 5, 2019 from the Churchill Northern Studies Centre. The outburst lasted only 5 minutes or so and might have been due to the Bz interplanetary field turning south briefly. After this series, the display faded and fractured into faint arcs and a diffuse glow across the sky. This is a single exposure with the 12mm Rokinon full-frame fish-eye and Nikon D750.
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!
A classic arc of aurora over the Northern Studies Centre near Churchill, Manitoba, on Feb 8, 2019. This was a night when both our Road Scholar group and a visiting Natural Habitat group was here. This is a single exposure with the 15mm lens and Sony a7III.
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!
A view of the weak (by Churchill standards) aurora display on Feb 3, 2019 as seen through my dormitory window at the Churchill Northern Studies Centre, to demonstrate how you can see the Lights from your room looking north.
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!”
A band of subtly coloured aurora over the snowy trees of the northern boreal forest, Churchill, Manitoba. This was Feb 9/10, 2019. Cassiopeia is at left. This is looking north. This is a single 6-second exposure with the Venus Optics 15mm lens at f/2 and Sony A7III at ISO 3200.
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!
A display of subtly coloured curtains over the Churchill Northern Studies Centre, on February 9, 2019. The curtains exhibited rapid rippling this night. This is 6 seconds at f/2 with the 15mm Venus Optic lens and Sony a7III at ISO 3200.
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 next sessions for the aurora are a year from now in February and March 2020. I’ll be there!
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.

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.

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.
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 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.
Last night, February 7, the Northern Lights danced for us again, starting with a curtain of green and pink in the south.
Our second tour group at the Churchill Northern Studies Centre has been here a couple of days, all under what looked like hopeless cloud. But last night the clouds cleared unexpectedly to reveal a moonlit winter sky.
I completed my evening talk all about the Sun and aurora, during which we were monitoring the auroral activity indicators on SpaceWeather.com. Sure enough, about 9:30 pm, right on cue and perfectly timed for convenience, a curtain of light began to dance across the southern sky, appearing in Orion. The gibbous Moon is just off frame to the right. We began the viewing from the Centre’s second floor viewing deck which looks east and southeast.
This view shows the auroral curtain over the derelict launch towers of the Churchill Rocket Range. Built in 1957 for the International Geophysical Year, the Rocket Range was in use until the mid-1980s as Canada’s only launch facility. Hundreds of sounding rockets, many of them Canadian-built Black Brants, were launched from here, shooting up into the ionosphere on nights just like this to study the aurora.
Orion is at right. While we saw this curtain in our southern sky, others farther south in Canada were seeing it in their northern sky. The greens were easy to see with the eye but the magentas were visible only by the camera and I have punched up their intensity here.
This night, as the aurora display developed it moved north to the zenith, shown here, with the sky also lit by moonlight and with some high haze. But the combination makes for a wonderful abstract swirl of light and colour.
Orion and Sirius shine over the abandoned launch towers of the Churchill Rocket Range.
This was the view Monday night, during a lull in the aurora display when I took a few moments to shoot the stars. You can see Orion at centre, with his trio of Belt stars pointing left and down to Sirius, the Dog Star in Canis Major, and the brightest star in the night sky. The Belt stars point up and right to Aldebaran, the brightest star in Taurus the bull.
They look closer to the horizon than you might be used to as this is from 58° north latitude.
These winter stars shine above some of the launch structures of the old Churchill Rocket Range. Built in 1957 for the International Geophysical Year, the Rocket Range served for many years as Canada’s only launch facility. No satellites were launched here. Instead the towers were used to launch sub-orbital sounding rockets into the ionosphere to explore the aurora.
Some of the rockets were repurposed military missiles, like Nikes and Aerobees. But many were Black Brants, civilian research rockets still being built in Winnipeg by Bristol Aerospace.
But no Black Brants take off from here now. The Rocket Range was shut down in the mid-1980s as Canada’s space program focused on satellites, the Space Shuttle, and sending astronauts into space. Attempts by private companies to revive the site have all failed and the structures are now becoming derelict, being too costly to remove.
The sky simply does not get any more amazing than this, as the Northern Lights dance across the heavens.
On the last night for our first aurora tour group of the season, the sky performed perfectly. Clouds cleared to reveal a star-filled winter sky, and after the evening talks and farewell drinks, the aurora began to appear. First it was a bright arc across the north, prompting me to try some self-portraits, as below.
But at about 2 a.m. a diffuse arc across the zenith exploded into activity, with rapidly waving and weaving curtains.
Everyone was awestruck. Some cheered and hollered. Others just watched in stunned silence. Some were busy with cameras. Others just enjoyed the view of a lifetime.
It was a cold night, but the aurora kept performing in waves, dimming for a time – allowing us to retreat to the warm cafeteria for hot chocolate. Then the display would brighten again to the west and a new wave of intensity would sweep across the sky to the east.
You didn’t know quite where to look to take it all in. The sight was overwhelming. Here the curtains ripple through Orion, Taurus and Auriga, all setting into the west.
The Churchill Northern Studies Centre has a new building opened in 2011 that is ideally set up for aurora watching. The building can go dark, and is located far enough from Churchill that local light pollution is not an issue. On the roof is a plexiglas dome where several people can view the Northern Lights and the entire sky in shirtsleeve comfort. The image is good enough for wide-angle photography. Sheer luxury!
But there’s nothing like being outside on a cold Arctic night, looking up and seeing this sight – thin curtains of light twisting and turning more quickly than you can take in and comprehend. It is one of nature’s greatest shows. And what a fantastic place to see it.
Tonight the aurora shone so brightly for a time it was visible through the cloud.
Here at the Churchill Northern Studies Centre we’ve been battling clouds all week. But on several nights the clouds have cleared for 30 minutes or more, enough to give us glimpses of the aurora and stars. Tonight, February 2/3, the clouds never did clear away enough for a great view. This was as good as it got, with the Northern Lights shining through haze and cloud but nevertheless filling the sky.
Remarkably, this was on a night when the usual indicators of auroral activity were registering all quiet. This shows the benefit of traveling north to stand right under the auroral oval, the zone of maximum activity. In this case I’m at 58° North, in Churchill, Manitoba. Even on a quiet night the Churchill sky can be filled with curtains of dancing colours.
Our tour group to see the Northern Lights finally saw what they traveled north to experience – the aurora borealis dancing across the sky.
This week and next I’m helping to lead some tour groups who have come to Churchill, Manitoba to see the aurora. We’ve been here 3 nights so far but last night was the first with clearing skies and when the Northern Lights appeared above us.
Our home base is the beautiful Churchill Northern Studies Centre, far enough from the main townsite to give us dark skies. Being able to sleep, eat and take in lectures (or for me, give lectures) right where we can see the aurora is a tremendous luxury and convenience. The Centre is perfectly set up for aurora viewing, with a rooftop dome, and the ability to “go dark” with all lights off.
Here in Churchill, on the shores of Hudson Bay, we are at a latitude of 58° north. But critically, we are right under the usual position of the auroral oval, the main band of Northern Lights that circles the world at high latitudes.
As such, even though last night the various aurora and magnetic field indicators were registering a quiet display with little disturbance in the field, we still saw a beautiful display. It wasn’t very active but did display curtains and rays shooting up to the zenith.
As seen here, for much of the time the main band of aurora was actually in the south. That’s Jupiter glowing through the aurora and thin clouds at upper right.
We’ve been fighting clouds all week but last night skies cleared for long enough and it seemed at just the right time to coincide with the brightest outburst of this display. After I took these images, the aurora died down to a more diffuse glow then the clouds thickened in again. By then it was 3 am and we all retired to our rooms.
