Auroras at Sea


Aurora from at Sea Near Lofotens #1

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.

Aurora over the Norwegian Sea #2 (Feb 27, 2019)
The Northern Lights over the Norwegian Sea south of the small fishing village of Oksfjord, from the Hurtigruten ferry ship the m/s Trollfjord on the northbound voyage from Bergen to Kirkenes. This was during a minor geomagnetic storm producing an all-sky aurora with a Kp Index however of no more Kp 3 – 4 this night. A break in the clouds allowed a glimpse of the Lights for about an hour at 11 pm. This is looking north. This is a single 1.6-second exposure at f/2 with the Venus Optics 15mm lens and Sony a7III at ISO 6400. Ship motion inevitably adds some star trailing.

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.

Auroral Swirls over Båtsfjord, Norway
Swirls of auroral curtains over Båtsfjord, Norway while we were in port on the southbound portion of the Hurtigruten coastal cruise on the ms Trollfjord. This was March 1, 2019. The stars of Taurus and the Pleiades are at left; Cassiopeia at upper right. This is a single 0.8-second exposure at f/2 with the 15mm Venus Optics lens and Sony a7III at ISO 1600.

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 Big Dipper is at upper right; Cassiopeia at lower left, and Polaris in the centre amid the aurora. This is a single 1-second exposure at f/2 with the Venus Optics 15mm lens and Sony a7III at ISO 3200. It was taken from port with the ship stationary and amid the port 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.

Aurora over Skjervøy, Norway
The Northern Lights over the village of Skjervøy on the northern coast of Norway north of Tromsø. Taken from the deck of the Hurtigruten ship the ms Trollfjord while in port, March 2, 2019. Looking west with Cassiopeia at right and the Pleiades at left. This is a blend of two exposures: a long 4-second exposure for the sky and aurora, and a short 0.8-second exposure for the ground and city lights. All at f/2 with the 15mm Venus Optics lens and Sony a7III at ISO 800.

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.

This is a 7-section panorama, handheld, with the Venus Optics 15mm lens and Sony a7III, stitched with ACR.

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.

Non-Stop Northern Lights


Aurora over the Boreal Forest (Feb 8, 2019)

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.

Aurora Group at Churchill Northern Studies Centre (Jan 31, 2019)
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!

Photographer Shooting the Northern Lights #2 (Feb 8, 2019)
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.

Auroral Arcs, Loops and Swirls (Feb 5, 2019) #5 of 5
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!

Auroral Arc over Northern Studies Centre (Feb 8, 2019)
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!

Aurora Thru the Dorm Room Window
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!”

Aurora over Snowy Trees (Feb 9, 2019)
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.

Auroral Arc over CNSC - Feb 2, 2019
An all-sky aurora over the Churchill Northern Studies Centre, captured with a fish-eye lens, Feb 2, 2019. This is looking northwest. This is a single 8-second exposure with the Sigma 8mm lens at f/3.5 and Sony a7III at ISO 3200.

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!

Coloured Curtains over CNSC (Feb 9, 2019)
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 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.

Enjoy!

If you are interested in attending one of the CNSC’s sessions — where you eat, sleep, learn, and view the Lights from a well-appointed and comfortable research centre at a dark site, check out the Study Centre’s “Learning Vacations” offerings.

The next sessions for the aurora are a year from now in February and March 2020.  I’ll be there!

Aurora Reflections in Yellowknife


Auroral Arc over Tibbitt Lake

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.

Aurora Panorama at Tibbit Lake #2

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.

Aurora in the Clouds Panorama

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.

The movie is in 4K. The music, Eternal Hope, is by Steven Gutheinz and is used by permission of West One Music.

Enjoy! And do share!

And make Yellowknife one of your bucket-list locations.

STEVE Puts on a Show


Steve Auroral Arc over House #2 (May 6, 2018)

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.

Aurora and Milky Way over Red Deer River

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.

Steve Auroral Arc over House #1 (May 6, 2018)

This is Steve to the west, displaying his characteristic pink and white tints.

Fish-Eye Steve #1 (May 6, 2018)

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.

Steve Aurora – May 6, 2018 (4K) from Alan Dyer on Vimeo.

It is in 4K, if you choose to stream it at full resolution.

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 Northern Lights from Norway


All-Sky Aurora from Norway #1

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.

Purple Auroral Curtains in Twilight from Norway
Auroral curtains in twilight on March 14, 2018 from at sea north of Tromsø, Norway, on the Hurtigruten ship the m/s Nordnorge, with the curtains showing a purple tinge at the tops, likely from scattered blue sunlight mixing with the red oxygen colours. The Big Dipper is at centre in a view looking north. This is a single 2-second exposure with the Rokinon 12mm full-frame fish-eye at f/2.8 and Nikon D750 at ISO 8000.

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.

Aurora Watchers on m/s Nordnorge #1

All observing and photography is done from the ship deck as we sailed among the fjords and sounds along the coast.

Purple Auroral Curtains from Norway

The Big Dipper is at upper left; Orion is at far right; Leo is left of centre, in a view looking south. This is a single 2-second exposure with the Rokinon 12mm full-frame fish-eye at f/2.8 and Nikon D750 at ISO 8000.

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.

All-Sky Aurora from Norway #3

The curtains are converging to the zenith at top. This is a single 1.6-second exposure with the Rokinon 12mm full-frame fish-eye lens at f/2.8 and Nikon D750 at ISO 8000.

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.

Entering Trollfjorden with Aurora
A scene from the Norwegian coast and the Loftoten Islands of the aurora over the entrance to the Trollfjorden fjord, from the forward deck of the Hurtigruten ferry ship the m/s Nordnorge. Cassiopeia and Perseus are at left. Vega (brightest) and Deneb are at lower right, high above the northern horizon from this latitude of 68° North. Taken March 10, 2018. I used the 14mm Sigma Art lens at f/1.8 and Nikon D750 at ISO 3200, for a 2-second exposure.

As is the custom, the captain enters the fjord by searchlight, a scene depicted below.

Entering Trollfjorden with Searchlights
A scene from the Norwegian coast and the Loftoten Islands of the aurora over the entrance to the Trollfjorden fjord, from the forward deck of the Hurtigruten ferry ship the m/s Nordnorge. The ship is using its searchlights to mark the entrance to the narrow fjord. Cassiopeia and Perseus are at left. Vega (brightest) and Deneb are at lower right, high above the northern horizon from this latitude of 68° North. Taken March 10, 2018. I used the 14mm Sigma Art lens at f/1.8 and Nikon D750 at ISO 3200, for a 2-second exposure.

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.

Panorama of the Auroral Oval from Norway
A 180° panorama of the sweep of the auroral oval, from due west, at left, to due east, at right, with due north near the image centre. Orion is just setting into the sea at far left. Cassiopeia is at centre. Deneb and Vega are the bright stars low in the sky and circumpolar shining just right of centre. I shot this on the evening of March 16, 2018 from at sea on the coast of Norway south of Rorvik, with the ship sailing south away from the aurora. This was from the aft deck of the m/s Nordnorge, one of the Hurtigruten ferry ships. The latitude was about 63° N. This is a panorama from 8 segments, stitched with PTGui, and shot with the Sigma 14mm Art lens at f/1.8, for a series of 1-second exposures at ISO 6400 with the Nikon D750.

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.

Sailing to the Northern Lights


Sailing to the Lights Title

I present a music video of time-lapses of the Northern Lights from Norway, shot from the ship the aptly named m/s Nordlys.

The Nordlys is one of many ferry ships in the Hurtigruten cruise line (the name means “fast route”) that ply the Norwegian coast, with daily departures from Bergen (at latitude 60° N) to Kirkenes at the top of Norway (at 71° N). At the top end of Norway you are under the auroral oval and almost always see some level of auroral activity, if skies cooperate.

This 11-day cruise was blessed with five clear nights with active auroras. I was serving as an instructor for a tour group of 30 from the U.S.-based Road Scholar tour company.

The final sequence is of the ship entering the Trollfjorden – a narrow fjord often entered in darkness under searchlight. This was a dramatic sight with the aurora dancing overhead.

For a selection of still images from this trip and from the second cruise I did immediately following, see my previous blog post, The Nordlys of Norway. 

Technical Info:
All exposures were about 1 to 1.3 seconds only, to minimize blurring during each exposure, shot with the Nikon D750 at ISO 6400, and with mostly the Sigma 14mm Art lens at f/1.8.

One sequence is with the Rokinon 12mm full-frame fish-eye at f/2.8. Intervals were 1 to 2 seconds, providing a rapid cadence.

In assembly I applied a 4-frame blur to smooth the frame-to-frame motion. All processing with Adobe Camera Raw and assembly with the Mac app Time-Lapse from MicroProjects.ca (an app no longer available – a pity).

Music is by the Hollywood soundtrack artists AudioMachine, and is used with permission under “social media” licence. It is the track “Above and Beyond” from their album Tree of Life.

The Nordlys of Norway


Nordlys Auroral Red Curtains #1

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.

 

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.
