Clearly visible night shining clouds - 12.7.2021 at 01.25 - 12.7.2021 at 01.55 Sysmä Observation number 99463

Visibility III / V

Arja-Sisko Airila, Ursa (Etelä-Suomi)

Illuminating night clouds were visible almost the entire length of the sky, most right in the zenith and also extended to the southern sky. I didn’t see the north direction properly because of the forest, but there also seemed to be high-reaching belts there. An arch resembling a horseshoe formed in the southern sky.

Pictures 1. south 01:31, 2. zenith 02:32, 3. north 01:36, 4. east 01:36, 5. south 01:53.
