Equipment: Naked Eye
Solarscope
Temperature: 5.1C

Notes:

Another hazy day, the haze seemed to be subduing the sunlight. More checking of the Sun to follow the progress of sunspot 822 and to see if 823 and 824 are still visible.

Like yesterday, sunspot 822 was immediately visible. It did, however, seem a little smaller than previous observations. I'm guessing this is down to the fact that it's getting more and more foreshortened as it heads towards the Sun's limb.

To: 2005-11-21 14:07 UT

With the Solarscope I could see sunspots 822 and 824 with no problems. However, I was unable to make out sunspot 823.

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:
