Aurora images

Fantastic aurora image was brought by solarham.com [7], this time from 21,000 feet in the air over Alberta, Canada taken by Matt Melnyk. “Here are some shots of last nights display from 21,000 feet. I am a pilot so I get a great view of the aurora from the cockpit. This was between 02:30 am and 03:30 am while flying to Fort McMurray from Edmonton at 21,000 feet.”
