Further to yesterday's observation about active area 898's appearance I could see that the umbra had broken up into 4 different spots — all surrounded by a common penumbra. The adjacent spot that I saw yesterday wasn't visible.

I could also see a new active area — 899 — coming around the limb of the Sun. Within it I could count 2 small, faint spots.
