Just had another look at Sol, and an extra group of two spots has appeared (or I missed it earlier!). A couple of extra spots were seen in another group, so now a total of 5 AAs and 19 spots. This gives an R of 69, which is the hightest I've recorded since I started monitoring last November.

Does anybody know how high R goes near a "typical" sunspot maximum? I guess this is 3 or 4 years away yet.

2021 September 05, at 1050 UT, seeing and transparency variable from fair to poor. I counted 4 spot groups, 3 south with 8, 6 and 3 spots each (from following to preceding) and 8 spots in the northerly group: total 25 spots. Equipment as before. Activity is picking up - there was one day in August that I counted 25 spots. Equipment as before. Bob

2021 Sun Sep 5th, 1254UT - seeing poor, image boiling

Grabbed a five minute break in the clouds for a quick look. Four groups seen -

12863 (S) - one big spot, one small one
12866 (S) - 5 spots, still with obvious faculae surrounding
12868 (S) - between 863 and 866, four spots
12864 (N) - two big, obvious spots with two smaller companions

The fifth (N) group from yesterday (12865) seems to have vanished!

Nice one despite less than the best observing conditions. The Sun is certainly worth viewing today using safe techniques of course.
Best wishes from Cliff.

Had another look this evening, at 1730UT, and saw an extra 5 spots for a total of 20.

I note that 12863 has a very round penumbra. Can't remember seeing one this round before.

2021 September 07 at 0855 UT seeing excellent and transparency good. I counted 4 spot groups comprising 22, 12 and 1 spots from following to preceding in the south and 7 in the north, totalling 42 spots in all. Very stable, detailed image on the screen that allowed for considerable enlargement without breaking down. Equipment as before. Bob

2021 Wed 8th Sep 1430UT, lousy seeing

Very hard to get the spots to focus. I had hoped that after a little bit of much needed rain earlier on, transparency would be good, but it wasn't!

Anyway, 5 groups, 3, 6, 9 and 1 spot(s) in the southern hemisphere, and 1 group/2 spots in the north.

2021 September 16, at 0915 UT, seeing excellent and transparency good. The image is steady but not a spot; only the shade of granulation at the solar surface casts an eye-whisper across the projected disc. Equipment as before. Bob
