All observing logs that mention sunspot 824

2005-11-23


Location: Billingborough (South Lincolnshire, UK)
From: 2005-11-23 13:56 UT
To: 2005-11-23 14:09 UT
Equipment: Naked Eye
Solarscope
Temperature: 5.5C
Humidity: 74%
Notes:

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.

Time: 2005-11-23 13:56 UT

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.

From: 2005-11-23 14:00 UT
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.

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.

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.

Sun with Solarscope

From: 2005-11-20 11:47 UT
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.
