Visibility I / V
In the yard, I went to the hustle and bustle to see if there were any illuminating night clouds. In the high east there were very dim night clouds as well as in the southern sky. To the west and north I did not see the situation because of the forest, and I could not go to a more open place to look at the situation. I still went out at 1:40 to look at the sky, but then only a very dim dim cloud of night clouds was visible in the eastern sky. Pictures taken with paperback with auto setting, so poorly visible in pictures. Exposure and contrast added to image processing with images. The sky was clear, calm, +22 degrees warm.
