Like yesterday the sky was completely clear. Decided to have yet another quick look at the Sun (4th day in a row) with the naked eye and with the Solarscope to see how sunspot 822 had developed.

Like yesterday, sunspot 822 was immediately visible — no effort was required to find it. Still a very clear, dark spot.

Set up the Solarscope for a better look at 822. Some changes were obvious when compared to yesterday's observation. The biggest pair of spots appeared to have fully merged into a single, large spot. The "tail" of smaller spots between the large pair and the smaller pair now appeared rather messy with some dark lines visible amongst them. The smaller pair of spots appear to have faded a fair bit.

Did the following sketch:
