The Norrthern Lights on Feb 16, 2015, as seen from the Churchill Northern Studies Centre, in Churchill, Manitoba at 58° latitude, and under the auroral oval. The aurora appeared as skies cleared somewhat during a blizzard with high winds and blowing snow conditions. I shot these from the second floor deck of the Centre, out of the wind and off the ground.
This is a 15-second exposure at f/2.8 and ISO 4000 with the 15mm full-frame fish-eye lens and Canon 6D.
