Quite a cloudy afternoon but with some gaps. During one gap I took the Solarscope out to do a quick sunspot count and, more to the point, to observe active area 904. |

I started by having a look at the Sun with the naked eye and a pair of eclipse shades. I could see the largest spot in active area 904 with no trouble at all. Next I pointed the Solarscope at the Sun. At first glance the area didn't look too different from yesterday. The biggest spot still had an impressively dark umbra and a nicely defined penumbra. Close by I could see a single, very faint spot-like mark — I didn't count this as a spot. The smaller pair of spots that I noted yesterday appeared to be a pair of pairs today (perhaps they were yesterday but the viewing conditions made it impossible for me to tell?). Each pair appeared to have a common penumbra and the penumbras of those pairs appeared to be joined. I quickly made the following sketch of the Sun in general:
I then attempted to sketch AA904 in a little more detail:
