Notes:

After getting my dates wrong yesterday, and having seen that the forecast was good again for this morning, I decided to have another go at getting up early and observing an outburst of Leonids activity that was predicted for around 04:45 UT.

The sky wasn't quite as clear as yesterday morning's session and, to start with, there was some thin cloud hanging around to the west but that cleared away during the session.

Leonids watch

From: 2006-11-19 04:29 UT
To: 2006-11-19 05:47 UT

I was set up in the garden, with chair and notebook, by 04:29 UT. I watched solidly from the chair for 1 hour. The following is a list of what I managed to catch along with the times that I saw them:

04:33 UT: Sporadic. West to east. Very short. Just south of Auriga.

04:36 UT: Leonid. Very short. Very fast. Through Auriga.

04:50 UT: Noticed the whole sky flash, just like I noted at 05:31 UT yesterday. Suspect it probably is a bird scarer in one of the fields around me.

04:55 UT: Leonid * 2. Almost together. Both short, fast and not very bright.

04:57 UT: Sporadic. North to south in Cancer. Short, fast and faint.

05:00 UT: Leonid. Short and fast. Through Auriga.

05:12 UT: Leonid. Short, fast and faint. Through Perseus.

05:13 UT: Leonid. Short, fast and bright. Left a visible trail that lasted a second or so. Just west of Leo.

05:14 UT: Leonid. Short and faint. Just south of Auriga.

05:18 UT: Satellite. Travelling roughly south/east to north/west through the zenith.

05:19 UT: Satellite. Travelling roughly south/west to north/east through the zenith. About the same speed and brightness as the previous one.

By 05:30 UT tiredness and the cold were really starting to get to me. Given that there'd been no obvious sign of the outburst I decided to pack up earlier than I'd planned and go and warm up. However, while packing up and moving things back into the office I managed to catch two more Leonids:

05:39 UT: Leonid. Short and very bright. Through Cassiopeia. Left a short wide trail that lasted a good couple of seconds.

05:47 UT: Leonid. Short and bright. Through Perseus.

If there was an outburst I didn't see any evidence of it. During this session I counted 9 Leonids — the same number as yesterday and over a similar period of time. I also counted 2 sporadics and noticed 2 satellites.

Very clear day. Took the Solarscope out to do a quick sunspot count.

Sun

From: 2006-11-19 12:40 UT
To: 2006-11-19 12:45 UT

The single spot in active area 923 still looked quite impressive but also even more foreshortened due to it being much closer to the limb of the Sun. I also checked with the naked eye (via eclipse shades) and, for the first time since I first observed it I was unable to see it.

I could also see 1 spot in active area 924 and 1 in active area 925.

Equipment: Naked Eye
Temperature: 3.9C ...
Dew Point: 1.4C ...
Humidity: 84% ...
Wind Speed: Calm ...
Pressure: 1000.7hPa ...
Notes:

Got up early with a view to observing the Leonids meteor shower. I'd read recently that a possible outburst of activity was predicted for around 04:45 UT but, stupidly, I'd got the wrong day (the outburst was predicted for the morning of the 19th, not the 18th). I didn't realise this until the session had ended (not that it would have stopped me if I'd realised as it started).

The sky was amazingly clear.

Leonids watch

From: 2006-11-18 04:39 UT
To: 2006-11-18 06:00 UT

I was set up in the garden, with chair and notebook, by 04:39 UT. For almost the next hour and a I just watched the skies and noted what I saw. The following is a list of what I managed to catch along with the times that I saw them:

04:47 UT: Leonid. Close to Polaris. Very bright. Very fast. Caught out of the corner of my eye.

04:51 UT: Leonid. Short, bright and fast. More or less directly overhead. I could see the resulting trail for a couple of seconds.

04:58 UT: Leonid. Very short, very bright. Just west of Leo. Resulting trail visible for a good couple of seconds.

05:01 UT: Leonid. Very short, very bright. Just north of Auriga. Resulting trail visible for a good couple of seconds.

05:07 UT: Leonid. Very short, not so bright. Straight through Auriga. Resulting trail visible for less than a second.

05:11 UT: Sporadic (I think). North to south, west of Leo. Looked just like most of the Leonids I'd seen so far.

05:13 UT: Leonid. Faint and short. West of Leo.

05:15 UT: Faint satellite seen going south to north through Auriga.

05:25 UT: Sporadic. Short and faint. No visible trail. South of Auriga going east to west.

05:31 UT: The whole sky lit up very briefly. The flash almost looked like lightening. Normally I might have thought it was a bird scarer but this was the only time I saw this happen during the whole session.

05:34 UT: Satellite. Very slow and very faint. Heading roughly south to north, just east of Auriga.

05:42 UT: Satellite. Heading roughly north to south through Auriga. Watched the brightness slowly decrease, until I could no longer see it, and then slowly increase again until it was reasonably bright. Watched it decrease in brightness again and then lost it behind the house.

05:46 UT: Leonid. Very short. Very faint. Just south of Auriga.

05:50 UT: Satellite. Faint and fast. Was going south to north and headed more or less directly overhead.

05:52 UT: Leonid. Reasonably long. Quite bright. Very fast. Seen out of the corner of my eye in the north east part of the sky.

05:55 UT: Leonid. Very faint, only just saw it. In the eastern part of the sky.

By 06:00 UT the sky was starting to noticeably brighten and the cold was starting to get to me so I decided to end the session. In total I noted 9 Leonids, 2 sporadics and noticed 3 satellites.

The single spot in active area 923 was still huge and impressive, although obviously foreshortened by being much closer to the limb of the Sun. I also checked with the naked eye (via eclipse shades) and I could just about see it, although it did take more effort than previous observations.

I could also see 2 spots in active area 924 and 2 in active area 925.
