Scenes from Under the Auroral Oval


Classic Curtains of the Auroral Oval

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!

Circumpolar Star Trails and Aurora (Feb 9, 2016)
Circumpolar star trails and aurora over the boreal forest at the Churchill Northern Studies Centre, Churchill, Manitoba, on Feb 9, 2016. This is a stack of 250 frames shot over one hour (until the battery died) for a time-lapse but here stacked for a single image star trail using the Advanced Stacker Plus actions and Long Streaks effect. Each exposure was 15 seconds at f/2.8 with the 15mm lens and Canon 6D at ISO 6400.
All-Sky Aurora from Churchill (Feb 5, 2016)
An all-sky aurora display of multiple curtains of aurora borealis over the boreal forest at the Churchill Northern Studies Centre, in Churchill, Manitoba, taken on Feb 5, 2016. The view is looking almost due north. Jupiter is at right. The Big Dipper is at centre frame. This is one frame from a 380-frame time-lapse sequence shot for digital dome projection in planetariums. This is a 20-second exposure at f/5 (stopped down by accident — should have been f/3.5) with the 8mm Sigma fish-eye lens and Canon 6D at ISO 3200. Temperature was -35° C. But no wind!
Observing the Aurora on Deck at CNSC
Participants in the Arctic Skies tour and course observe and photograph the Northern Lights from the upper level observing deck at the Churchill Northern Studies Centre, Churchill, Manitoba on Feb 10, 2016, the first night of their tour. A Level 1 to 2 display provided a good first night show though with bitterly cold temperatures and wind chills of near -50° C. This is a single exposure of 8 seconds at f/1.4 with the 20mm Sigma Art lens and Nikon D750 at ISO 3200.
Aurora over Churchill Northern Studies Centre #1 (Feb 8, 2016)
The Northern Lights over the Churchill Northern Studies Centre on Feb 8/9, 2016 during a weak all-sky display. The arcs lay primarily in the south when the display was at its best this night. Orion and the Pleiades are just setting in the west over the town of Churchill. This is a 20 second exposure at f/2.8 with the 15mm full-frame fish-eye lens and Canon 6D at ISO 3200.
Northern Lights Panorama #2 from CNSC Deck
A panorama across the northern horizon of the sweeping curtains of the aurora, taken from the observation deck of the Churchill Northern Studies Centre, Manitoba. I shot this on Feb 10, 2016 on the first night of the Arctic Skies tour group week. Vega is low in the north at left of centre, Arcturus is the bright star at right of centre. This is a 4-segment panorama, stitched with Adobe Camera Raw, with each segment 5 seconds at f/1.4 with the 20mm Sigma lens and Nikon D750 at ISO 3200.
Aurora with Leo and Jupiter Rising (Feb 5, 2016)
Curtains of the aurora looking northeast and east toward Leo rising (at upper right) and Jupiter (at right), over the boreal forest of the Hudson Bay Lowlands near Churchill, Manitoba, on Feb 5, 2016. This is a single frame from a 680-frame time-lapse. This is a 4-second exposure at f/1.4 with the Sigma 20mm Art lens and Nikon D750 at ISO 3200.
Vertical Curtains of Aurora over the Boreal Forest
Vertical curtains of aurora converging to the zenith overhead over the snowy boreal forest at the Churchill Northern Studies Centre, Churchill, Manitoba. I shot this Feb 4, 2016 on a night with temperatures of -35° C with a slight wind. The Big Dpper is at right. Exposure was 10 seconds at f/2.8 with the 15mm lens anf Canon 6D at ISO 3200.
Gazing at the Aurora from Churchill
A lone figure gazes skyward at the aurora over the Churchill Northern Studies Centre, Churchill, Manitoba. I shot this Feb 4, 2016 on a night with temperatures of -35° C with a slight wind. Exposure was 13 seconds at f/2.8 with the 15mm lens anf Canon 6D at ISO 3200.
Aurora, Big Dipper and Polaris
A wide vertical portrait of the Northern Lights in the northern sky, with the stars of the Big Dipper and Polaris above centre. Shot from the upper deck of the Churchill Northern Studies Centre on a very windy night with wind chills of -50°, so standing in the wind to take this image was bitter! You grab a few images and retreat! This is a single 15-second exposure at f/2.8 with the 15mm lens and Canon 6D at ISO 3200.
Arctic Skies Group Under the Aurora
The February Arctic Skies tour group watching and photographing the aurora from the second floor deck of the Churchill Northern Studies Centre, where it is out of the wind, which this night was producing -50° C wind chills. This is a single 6-second exposure at f/2.8 with the 15mm lens and Canon 6D at ISO 6400.
Watching the Aurora in the Winter Stars
A self-portrait of me watching the Northern Lights from the upper deck of the Churchill Northern Studies Centre, looking south to the winter stars of Orion, Gemini and Auriga. This was Feb 11, 2016, a very windy, almost blizzard night with blowing snow and reduced visibility. However the aurora did appear through the haze and clouds. In the distance are the buildings of the old Churchill Rocket Range. This is a single 15-second exposure at f/2.8 with the 15mm lens and Canon 6D at ISO 3200.
