Here are a couple of
realtime videos of the Aurora display on 11 May. Same location as
the photos. Turn down the lights for best results. Quality is pretty average. The 6D wasn't really designed for this but you can see what's going on. Ignore the pixel-scale noise - all other movement was real. Yes, it moves that fast.

The FoV is 100°+ diagonally.
