The first session of this obsering season! The season starter happened again in the Cygnus -summer meeting of Finnish amateur astronomers. In the early night, I was observing noctilucent clouds, and I started this session when the darkest moment of the night was already over. The nights are still light and short in this time of the year here up north, and this is why I was able to do only one observation. This time the first object observed was star R Tri, whose brightness was 6.6 mag.
