A participant in the February Arctic Skies tour sets up a photograph of the aurora in the northern sky from the deck of the Churchill Northern Studies Centre, Feb 11, 2016. The Big Dipper and Polaris are above centre. This is a single 15-second exposure at f/2.8 with the 15mm lens and Canon 6D at ISO 3200.
Multiple curtains of aurora appear along the curving arc of the auroral oval over the boreal forest. This is looking just a little east of due north from the second floor deck of the Churchill Northern Studies Centre, Churchill, Manitoba. Polaris is just left of top centre, with the Big Dipper at right of top centre. A meteor streaks to the left of Polaris. Vega is at lower left as a circumpolar star low in the north. The curtains appear more yellow toward the horizon due to atmospheric absorption. The curtains display the classic green tint with red upper fringes, both from transitions in oxygen. This is how the Lights usually begin from this latitude under the auroral oval. They will then move up and south from this formation to cover the sky. This is a 20-second exposure at f/2.8 with the 15mm full-frame fish-eye and Canon 6D at ISO 3200.
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!
