A frame from a 300-frame time-lapse taken June 28, 2013 during an all-sky aurora display seen widely over North America. This was taken from the Wintering Hills Wind Farm on Highway 56 south of Drumheller, Alberta. It is a 25-second exposure at f/3.5 with the 8mm Sigma lens and Canon 5D MkII at ISO 1600. The waning quarter Moon is just rising at left, with the auroral sub-storm beginning to peak.
