Quite a hazy day, some wispy cloud in the sky, some of it passing the Sun. Checking the Sun again to follow the progress of sunspot 822, to see if 823 was still visible and also to try to catch a glimpse of 824 — a new spot that was coming around the Sun's limb.

Like yesterday, sunspot 822 was immediately visible — no effort was required to find it. Still no obvious difference to the naked eye.

With the Solarscope, 822 looked more or less the same as yesterday. 823 seemed a little more obvious. I could also see 824 without any problems.

Did the following sketch of the whole of the Sun to show the positions of the spots as I could see them in the Solarscope:

Also did the following sketch of sunspot 822:
