Visibility IV / V
The only night clouds in Cygnus 2014. The night clouds appeared just before midnight, and they were still visible when I went to bed at 2:30.
The night clouds were in the sky in a sector extending from northwest to east and their maximum height measured from the northern horizon was 110 degrees at best. Later in the night, the play was clearly divided into two in the northwest and northeast.
The night clouds were quite bright, the average brightness in the play was of the third grade, with the brightest forms being Nelonen level. There was almost everything possible in forms. Roughly classified, however, this play was perhaps a belt-wave type play. Tropospheric clouds hampered detection slightly.
I also wrote about the play on my blog .
