Visibility IV / V
The night cloud situation in Irci was monitored. By half past one, the Nightingales were visible, although the lower clouds were a nuisance here and there. The top play was wide, dim, continuing 60 ° above the zenith from east to northwest. The brightest forms were brightness k = 4, although the general appearance was "clearly visible". Of note was the broad grouping of waves in the northwest direction. In addition to them, there were basic belts.
By 1.00 a.m., the play had usually froze. Of course, the brightness in the best forms is still k = 3. The shadow of the earth clearly had an effect on this, although I do not think that the reduction in intensity will be fully understood.
