Awesome Aurora Above Calgary May 7 2016 by Larry McNish

During the University of Calgary's Rothney Astrophysical Observatory "Open House Night" on May 7-8, 2016, the public and the gathered astronomers were treated to an awesome aurora display that lasted hours and covered more than half the sky.
Here is an 5½ hour time-lapse of the amazing display above the observatory compressed into just a couple of minutes.

Great. That night was special on many levels. I was a newcomer and that night I fell in love with this country. I spent most of the night laying down on my backyard. I've seen many auroras since but this one was so strong and colorful and lasted for so long AND was so high on the sky not only near the horizon. Great memories
