Clearly visible night shining clouds - 26.7.2021 at 01.00 - 26.7.2021 at 02.33 Juva Observation number 99945

Visibility III / V

Petri Martikainen, Ursa (Itä-Suomi)

Last night night clouds from the north. Main photo taken at 1:27, timelaps video from 1:30 to 2:33. All images in the video were shot with the same settings, so the sky brightens towards the end. Even the raw image of the video can be found by dealing with weak night clouds. The sun is then still 7.5 degrees below the horizon.
