Details:
What a great display! On June 22, the aurora was active as soon as the sky got dark enough to see the display in our bright solstice twilight, which at my latitude of 50° N wasn't until after 11 pm MDT. The display reached up to the zenith, as seen in the all-sky fish-eye images. However, it was apparent we here in western Canada were seeing the end of the display that had been going on for hours. The aurora was most intense early in the evening, with a minor outburst about 11:30 to 11:45 pm MDT. The aurora then subsided in structure and turned into a more chaotic pulsating display, typical of the end of a storm. By 1 am MDT the display, while still widespread over a large area of the northern sky, had turned into a diffuse glow. I shot with 3 cameras, taking hundreds of frames for time-lapse movies. These images are samples from two of the cameras, one with an 8mm fish-eye for a sequence suitable for projection in a digital planetarium, and one with a 15mm wide-angle lens looking north toward the glow of perpetual twilight over Crawling Valley Lake in southern Alberta.
