Active areas 921 and 922 both appear to have calmed down quite a bit. AA921 contained just 2 spots (one of them appeared to have a rather nice "tail" associated with it) and AA922 had just 1 small spot.

Active area 921 appears to have developed a little more when compared to yesterday. Today I counted 12 spots of varying sizes. The "double spot" I saw yesterday now appeared to be a single spot within a penumbra.

Active area 922 appeared to have developed a little more too and now contained 5 spots.

Active area 921 appears to have developed even more when compared to yesterday. Today I counted 11 spots of varying sizes. The spot that I saw yesterday, that appeared to be developing a penumbra, now appeared to be two spots sharing a common penumbra.

Active area 922 appeared to have developed a little more and now contained 3 spots.

Another clear night with an 82% waxing Moon. Despite the extra moonlight the sky actually seemed slightly better than last night. Decided to head out and have another look for comet Swan.

Tracking down comet M4 Swan

From: 2006-11-02 19:30 UT
To: 2006-11-02 19:37 UT

First I stepped outside with my 10x50 binoculars to see if I could find comet Swan. It took a minute or two of sweeping around the right area but I finally managed to find the comet. It was quite hard to see, just a small, faint fuzzy patch. When compared to M13 it looked to me like the comet and the cluster were equally hard to see and both about the same brightness.

Comet M4 Swan with the 905

From: 2006-11-02 19:40 UT
To: 2006-11-02 20:02 UT

At 19:40 UT I took the Antares 905 out into the garden to let it cool off for a short while.

At 19:52 UT I found the comet using the 32mm eyepiece. As with the view by the binocular the comet looked small, faint and fuzzy. I also found that it was almost impossible to see with direct vision. There was no sign of a tail.

I next switched to the 15mm eyepiece and the view didn't seem any different. It was just visible with averted vision but generally disappeared when using direct vision. I could no longer make out the central brightness that I could easily see a few nights back.

I switched to the 10mm eyepiece and the view seemed much better (but sill nowhere near as good as the previous views). The comet now withstood direct vision although averted vision still gave the best view. The best description was still that of a "faint fuzzy patch".

Finally I used the 6mm eyepiece. The view was pretty much the same as that via the 10mm. In all the different eyepieces there was no hint of the tail at all.

Given that conditions were far from ideal for the comet I decided to give up on observing it for this session and to take a short break.

Attempt at imaging the Moon

From: 2006-11-02 20:32 UT
To: 2006-11-02 21:00 UT

After the short break I decided to have a go at imaging the Moon, via the 905, using a little digital camera I'd recently purchased (an Olympus FE-115). I wasn't expecting anything spectacular but I was interested to see how well it might work using afocal projection.

I spent the next 25 minutes or so trying different combinations of settings on the camera and different eyepieces in the 905 and found that the 32mm eyepiece along with maximum optical zoom on the camera gave the best results. Sadly even these results weren't terribly good.

The main problem seems to be with the fact that the camera is auto-focus and it was failing to get useful focus on the Moon. I could see, as it was seeking focus, a nice sharp image and then disappear as it finally settled in the wrong place. Ideally it would have a setting that would force it to focus on infinity. To the best of my knowledge it has no such setting (I'll have to go and read the manual again to double check).

Sadly even the best image acquired is pretty terrible so there's little point in including any of them in this log.

Active area 921 appears to have developed even more when compared to yesterday. Today I counted 9 spots of varying sizes, at least one of which seemed to be developing a penumbra.

Active area 922 was sill visible with a single small spot.

Location: Billingborough (South Lincolnshire, UK)
From: 2006-11-01 19:15 UT
To: 2006-11-01 19:25 UT
Equipment: 7x50 Binoculars
Temperature: 4.9C ...
Dew Point: 1.1C ...
Humidity: 77% ...
Wind Speed: Calm ...
Pressure: 1029.5hPa ...
Notes:

Clear night but the sky was washed out by the light of a 75% (approx) waxing Moon. Despite the conditions I decided to get the 7x50 binoculars out to have a quick look for comet Swan.

Comet M4 Swan

From: 2006-11-01 19:15 UT
To: 2006-11-01 19:25 UT

I swept around the general location of comet Swan with the 7x50 binoculars but failed to find it. This wasn't that surprising given how washed out the sky was. I struggled to see the Keystone in Her with the naked eye and, with the binoculars, M13 was almost impossible to see.


2006-10-31


Location: Billingborough (South Lincolnshire, UK)
From: 2006-10-31 15:30 UT
To: 2006-10-31 15:35 UT

Wind Speed: 2.9mph ...
Wind Dir: North West ...
Pressure: 1005.5hPa ...
Notes:

Overcast and stormy for most of the day but started to clear a little into the late afternoon. While I had the chance I took the Solarscope out to do a quick sunspot count.

Sun

From: 2006-10-31 15:30 UT
To: 2006-10-31 15:35 UT

Active area 921 had developed quite a bit and looked a lot stronger than yesterday. I counted 5 sunspots, all quite small.

Close by I could also see another single spot but I wasn't sure if this was in a separate active area or was part of 921. Checking later it turned out that it was part of new active area 922.

Notes:

Reasonably clear evening, if a little hazy. The view of the sky was made worse by a 61% waxing Moon.

Comet M4 Swan

From: 2006-10-31 19:15 UT
To: 2006-10-31 19:20 UT

Annoyingly I didn't have the available time to do a proper observation of comet Swan so I quickly grabbed by 7x50 binoculars and went outside for a few minutes to see if I could still find it.

I found it almost right away, a small fuzzy patch just off the bottom left hand corner of the Keystone in Her. I compared it with M13 and I would say that the comet still looks brighter.
