The day started off very clear but, by the time I got out with the Solarscope to do a sunspot count, plenty of cloud had started to gather. The count had to be done in fleeting clear moments.

Active areas 897 and 898 were both nicely visible without any trouble. I could count 4 spots in 897 (down 1 from yesterday), I got the impression that the whole area had faded a little too.

Area 898 still had a the large spot I could see yesterday, the umbra appeared very dark, the edges look quite sharp. It is still surrounded by a very obvious penumbra. I could also see a second spot in the area, much smaller than the main one.
