Weather: Clear sky, moderate wind, last quarter of Moon low in the eastern sky, humid air, 4°C
Objects observed: SS Cyg (visual), R Cyg (visual), R Tri (visual)
During the first session in September, the sky was relatively dark and transparent, although the last quarter of the Moon was in the sky. It was at quite low altitude, which helped situation. SQM was almost 21 and NELM was about 6,5! This time I observed variable stars. I observed SS Cyg, R Tri and R Cyg. SS Cyg has now returned to it’s faint state (normal brightness). R Tri and R Cyg are both getting fainter.It would have been fun to observe for even longer time, but because I had to be working next day, I had to go to bed early, so that i could sleep even a little before waking up in the morning.
