The all-sky aurora of June 22, 2015, during a level 7 to 9 geomagnetic storm, as the display began already active in the twilight of a solstice night. This is one frame from a 960-frame time-lapse, taken with the 15mm full-frame fish-eye lens at f/2.8 and with the Canon 60Da, looking north to the perpetual twilight of solstice. I was on the south shore of Crawling Valley Lake and Reservoir in southern Alberta. (Photo by: Alan Dyer /VW PICS/UIG)
