Clearly visible night shining clouds - 12.7.2022 at 00.05 - 12.7.2022 at 01.30 Vantaa, Pähkinärinne Observation number 107622

Visibility III / V

Paula Wirtanen, Ursa (Helsinki)

Shortly after midnight, I noticed illuminating night clouds quite clearly visible from the kitchen window. I set out to take a closer look at them, but the sky was partly cloudy and it was only clear to the west and northwest. However, the night clouds were quite high and I would estimate that there was 1/8 of the sky.

The shape in the northwest was belts (pictures 1 and 2). Especially in picture 1, the belt just above the tops of the fir trees was clearly brighter than the others.

There were clouds high up in the northern direction, but a wave-like formation was clearly visible behind the cloud cover (picture 3).

I went back to the observation site even later, although I was already planning to sleep, because the sky seemed to have cleared somewhat and there was a night cloud resembling a feather or a large feather (picture 4; the stars of Cassiopeia were not distinguishable with the naked eye). A rather lumpy and vague shape also stood out (picture 5). The brightness was the same, but now the scope of the play had increased.

    • Unusual forms info

      Relatively rarely, there are special shapes in the night shining cloud displays that do not belong to the shapes listed above. Such may be, for example, thick lumpy formations that appear as some kind of patches. They may also be associated with an unusual color tone.
