Nice colours. How faint were these auroras as seen with your own eyes?
I also noticed the aurora yesterday. I first noticed it because I was working calibrating the meteor cameras that we've installed at Gaustatoppen (1846 masl) in southern Norway, so I saw it on screen before I looked out of the window
. Still very experimental as this summit has some of the most extreme weather in Norway. Since clear weather had been forecast, we had just removed
the 5 cm thick layer of ice that had formed on the camera dome over the past week (we're still working on better heating solutions) and the clear sky was an opportunity to calibrate the cameras. The aurora was a bonus (and it didn't last all night, so the calibration wasn't spoiled by it). The cameras record at 25 fps, and I think the sensitivity is quite decent.
EDIT: inlining Youtube didn't work for some reason, so here's the
