Very warm, clear, calm day. Some thin cloud around but nothing to get in the way. Took the Solarscope out to do a sunspot count.

Active area 897 was still visible but each of the spots in it seem to have faded a little when compared to yesterday. I could count 5 spots in the area (which is actually 1 up on yesterday — probably helped by better conditions today).

The main spot in area 898 still looked crisp and strong with a very dark umbra and quite a thick penumbra. I could still see a second spot in the area which was still much smaller and fainter than the main one.
