All observing logs that mention sunspot 823

2005-11-21


Location: Billingborough (South Lincolnshire, UK)
From: 2005-11-21 13:52 UT
To: 2005-11-21 14:07 UT
Equipment: Naked Eye
Solarscope
Temperature: 5.1C
Humidity: 86%
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.

Time: 2005-11-21 13:52 UT

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.

From: 2005-11-21 13:57 UT
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:

2005-11-20


Location: Billingborough (South Lincolnshire, UK)
From: 2005-11-20 11:44 UT
To: 2005-11-20 12:00 UT
Equipment: Naked Eye
Solarscope
Temperature: 4.6C
Humidity: 86%
Notes:

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.

Time: 2005-11-20 11:44 UT

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

To: 2005-11-20 12:00 UT

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.

2005-11-19


Location: Billingborough (South Lincolnshire, UK)
From: 2005-11-19 12:28 UT
To: 2005-11-19 12:44 UT
Equipment: Naked Eye
Solarscope
Temperature: 4.0C
Humidity: 83%
Notes:

Cold, rather hazy day. No cloud visible. Decided to have a look at the Sun (5th day in a row) with the naked eye and with the Solarscope to see how sunspot 822 was progressing.

Time: 2005-11-19 12:28 UT

Like yesterday, sunspot 822 was immediately visible — no effort was required to find it. I've seen no obvious change in it, with the naked eye, over the past few days.

Sun with Solarscope

From: 2005-11-19 12:34 UT
To: 2005-11-19 12:44 UT

With the Solarscope I could see a new, small, pair of spots some distance from 822. I checked on SpaceWeather.com but couldn't see any mention of them (although the image being displayed at the time was from yesterday) so I don't know if they have an ID.

Subsequent checking showed that they'd been given the number 823.

Sunspot 822 hadn't greatly changed a whole lot from the previous day.

Did the following sketch:
