Bright night shining clouds - 10.7.2020 at 00.35 - 10.7.2020 at 02.50 Espoo Observation number 91772

Visibility IV / V

The clock was ringing 0.30 when I had slept past the night clouds the night before. A glance at the balcony door and the clothes on. Walking to the nearest open place to admire the bright night cloud display. It was a wonderful summer night anyway. Occasionally fog formed at low points. By two o'clock, ordinary clouds began to fall from the southwest, and they occasionally covered part of the sky. Just under three night clouds were visible in the zenith among ordinary clouds.

Pictures are from 01.10 to 01.25.

Kiitos Markku! Pitkään aikaan paras yöpilvinäytös, joka on kohdalleni osunut. Harmitti kun oli aikainen aamu eikä voinut oikein lähteä pidemmälle esim. järven rannalle kuvaamaan.
