Bright night shining clouds - 27.7.2021 at 23.25 - 28.7.2021 at 01.00 Rusko Observation number 100016

Visibility IV / V

Mikko Peussa, Ursa (Länsi-Suomi)

At first I thought of a new category of “night clouds through the clouds” because they were really visible through the clouds. Finally, the sky was pretty cloudless with night clouds, so I chose bright night clouds.

The first belts were separated from the cloud holes at 11:25 p.m.
