During this session, I was making observations in the parking place of the Seitseminen Visitor Center in Seitseminen National Park, Finland. The place is considerably dark when the yard lights have turned off in the late evening. Still there are two door -lights shining, but it is easy to hide those lights behind trees in the parking lot.This time I was observing star SS Cyg for first time in my life, and I was happy to see, that an eruption was going on, and th star was in it’s bright state! Besides this dwarf-nova, I also observed U Umi and R Tri.
