Clearly visible night shining clouds - 14.7.2013 at 00.48 - 14.7.2013 at 01.30 Hausjärvi Observation number 16063

Visibility III / V

Conditions in Hausjärvi were difficult. The northwest-north direction was hazy and the night clouds were very faintly visible. In the northeast-east direction, there were lower cloud ferries as an obstacle. However, there was such a clear and bright line over the zenith that I considered it flying. The van was relatively straight at first, but then began to curve and widen, but still quite slowly. However, for the sake of certainty, I took a couple of pictures at 0:48 and 1:19. Would I have happened to be directly under the Helsinki cloud worm?

Jos tuo yöpilvipyörre (IVc) olisi ollut Helsingistä katsoen, sanotanako vaikka 50 asteen korkeudella, niin aiemmin viittaamani yöpilvioppaan taulukon perusteella etäisyys yöpilveen olisi ollut 70 km.  Lienee aika hyvin Hausjärven etäisyydellä?

Jep. Menee ihan nappiin. Havaintopaikka oli n. 7 km Hausjärveltä pohjoiseen. Kesän erikoisimman pilven sijasta sitten käytin havaintoajasta suurimman osan suttuisen horisontin tuijottamiseen. Vanha niska ei taivu enää niin hyvin zeniittiin.
