Dim night shining clouds - 24.7.2021 at 01.34 - 24.7.2021 at 03.06 Helsinki Observation number 99887

Visibility II / V

When I last looked at the situation from the window at 1 o'clock, I thought the watercourse was coming. But no, half an hour later a small cluster of night gauze appeared in the north which, from about 2.20 am, expanded even to the northwest side while rising higher. The image is a video compilation of 126 frames for the entire review period.
