Visibility IV / V
After half past two, I got a nice alarm: northern lights! I'm not in a hurry to look at the observation site. Fortunately, in addition to the dim aurora arc, there were also unexpectedly illuminating night clouds in the sky.
The night cloud show was in a really, really small area and right next to the horizon, but they were bright. The shape of the night cloud was also peculiar. As for the photography, the recording went quite poorly and the end result cannot be called very beautiful. Fortunately, at least Toni Maurinen from Imatra got a nicer and more accurate picture of the night clouds.
All in all, however, a situation worth seeing is to see these two nice light phenomena at the same time in the sky, even if in a more modest way. Thanks to Veikko Mäkelä for the fuss.
