what did it look like as far as what you could actually see with your eyes?
I used video from one of our meteor cameras, I wasn't even there, if I had been there, it would look like pretty regular aurora but it was more popping up here and there than a continuous display, so the stack doesn't get too washed out and it looks a bit like something that actually could happen if the sky really exploded in aurora (perhaps a bit over the top, but not too far from something that could possibly happen).
what do you use to stack videos? I assume you extract the individual frames?
I decode the video frame by frame and for every pixel in a certain position I store the one which has been the brightest in that position. And finally some simple post processing to reduce noise. In all about 18,000 frames (20 minutes, 15 frames per second).
the little streaks that are visible embedded in the display, are those meteors?
No, star trails. This is like a 20 minute exposure, but because no single exposure is more than 1/15th second, I avoid overexposure.
