Clearly visible night shining clouds, Imatra, Onnela

I waited for the sky to darken in front of the computer. The first warnings came from Matias Takala already in the midnight countries. True, the first time we went outside at 0.15, the night clouds were already clearly visible.

The play turned out to be extensive. Especially the east, southeast and south (!) Directions dominate. At its southernmost, the night clouds were visible at a height of twenty degrees from the southern horizon.

Even in the north, night clouds were visible, but due to the brightness of the sky, that direction remained weak. There were no very bright ones in the west either, even though the cloudy area reached out there dimly.

It seemed that the farther east Finland was observed, the better the night clouds were visible. I saw that I was quite in the desert tonight. The play seemed to improve as the night progressed.

The play was very diverse. Almost every form was found. If the play is to be typed into something, it was mainly the case of the belt-vortex type, but there were plenty of spotty night clouds among them.

The brightness was at best k = 3 (clearly visible), almost brightness 4. However, the bright sky ate the contrast, so for the marked k = 3 value.
