Eye-catching night shining clouds - 10.8.2022 at 01.40 - 10.8.2022 at 02.50 Turku Observation number 108247

Visibility V / V

Mikko Peussa, Ursa (Länsi-Suomi)

At this point in August, the illuminating night clouds remain low and in a small part of the sky in the Turku region, but in terms of their beauty, these were the best of the season for me.

It's great that it's still summer vacation and anyway I'm most cheerful at night. The night clouds of the early night were very quiet compared to these. These night clouds came as if reborn into the morning night sky.

EDIT: A couple of gif animations at the end. In the faster version (targeted images), you can see more clearly how the border between light and shadow changes at this time of year at the height of the night clouds.
