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.

Very clear day, quite breezy too. Took the Solarscope out to do a quick sunspot count.

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.
