Clearly visible night shining clouds - 13.8.2021 at 01.40 - 13.8.2021 at 02.00 Mustasaari Observation number 100533

Visibility III / V

Tommi Järvilehto, Vaasan Andromeda

The maximum night in Perseidite was cloudy from the beginning. I noticed at 1:00 that the clouds had receded

There were also illuminating night clouds as a surprise. Were somehow look though a small area and down the northern horizon. Perhaps the contrast was greater when they were just visible at the time of maximum darkness. In addition, there were a few bright vertical lines.

The clouds watched after about two o'clock.

The first image is cropped from the latter original.
