Quite a hazy day. As with my last observation the haze seem to be subduing the sunlight. Decided to have another look at the Sun to see if I could still see sunspots 822 and 824.

Sunspot 822 with naked eye

For the first day since I started observing sunspot 822 I was unable to see it at all with the naked eye. This might have partly been down to the sky been so hazy.

Sun with Solarscope

To: 2005-11-23 14:09 UT

With the Solarscope I could see sunspots 822 and 824 with no problems. 822 now looks mostly like just two spots, one large one that still has a very obvious penumbra and a smaller one with no visible penumbra. 824 appeared as two spots, one bigger than the other, both slightly "fuzzy", neither having a visible penumbra.

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. Note that the smudged area near 822 didn't look quite that obvious, it's there to mark an area where there was some faint mottling on the Sun's surface and where I thought I could see some very small, faint spots.
