Vastapilvisäteet - 18.8.2014 at 21.15 Laihia Observation number 29233

Visibility III / V

Esko Lehtiniemi, Lakeuden Ursa

Such rays opposite the sun. I didn't find any information in the cloud with radius from the info button. When browsing previous observations, it seems to be counter-cloud rays. The twilight rays look different and only appear after sunset. At the time of shooting, the sun was still above the horizon, but behind a high and thick cloud.

      Vastapilvisäteet ovat Aurinkoa vastakkaisella taivaalla näkyviä säteitä. Vastapilvisäteet raportoidaan silloin kun Aurinko on horisontin päällä. Auringon ollessa horisontin alapuolella raportoidaan vastahämäränsäteet.
