Last quarter next Monday (December 31), means the Moon will be a waning crescent for the Quadrantid maximum, due next Friday morning, January 4, around 06:40 UT. The Moon will rise only around or after 05h UT for most of Britain then. The shower peak is typically short and sharp, so this maximum timing may be a little too late for the UK if it proves accurate, with morning astronomical twilight beginning between roughly 06:00-06:20 UT for sites here. However, rates should still be worth seeing as they rise towards the maximum overnight on January 3-4. Although the shower's radiant is circumpolar in northern Boötes, at 15h20m RA, +49 degrees Dec, it is very low during the first half of the night, and is only properly observable after midnight. The maximum Zenithal Hourly Rate (ZHR) for the Quadrantids has been around 120 in recent times, though it does vary somewhat from year to year, sometimes as low as 60, at others up to 200, and has occasionally persisted for a couple of hours (as most recently in 1998). The peak time may alter slightly too, and additional maxima, perhaps of predominantly fainter meteors, may precede and follow the main event by half a day or so. Quadrantids are of medium-speed, often reasonably bright near the visual maximum. Much lower, often negligible, numbers of them should be present from about January 1-5.

For more information on these and others of January's showers, see: http://www.popastro.com/sections/meteor ... an2008.htm elsewhere on the SPA website. Good luck!

I will be sure to forward all my results onto you Alistair

Clear skies :-)

Went out at midnight and then looked at 4 and 5am
Complete blanket of cloud from horizon to horizon on the Surrey/Berkshire border.

Any results from elsewhere?

Thanks
DT

The question maybe "why?" but the answer is usually "why not?"

The night of the 3rd/4th January was completely clouded out for me here in Preston.

I have posted my own radio observations to the gallery here.

You can see more radio-meteor results at the following link.

Good luck with your own observation.

The Quadrantids were a complete washout (snowout/rainout, etc., as has been the whole of January so far) for me in Northumberland too. I've had no positive UK reports as yet at all on the event, apart from David's radio data. NASA were intending to try some aerial observations during the shower again - see David's General Chat Forum posting for details, at:

http://www.popastro.com/phpBB2/viewtopic.php?t=8099 .

The IMO currently has a "live" Quadrantid webpage showing how the early visual reports suggest Quadrantid activity behaved, available off the homepage at:

http://www.imo.net .

This morning, it was showing an unusually weak Quadrantid maximum, with ZHRs at best only ~65 +/- 3 around 04:30 UT on January 4, earlier than expected, and also significantly earlier than David's radio data indicated. No doubt this all can be clarified as more results come through (he typed hopefully...).

Naturally, if anyone has any positive observations from the shower, I'd be delighted to see them!

Saw a meteor last night whilst out doing my variable star work

It was around 00.15, 5th January 2008, Mag 2.0 and followed the horizon for 1.5 seconds below Cepheus. Not sure though if this was a quad or a sporadic. No Train.

Hope this helps

Dave

Thwarted once again by the weather gods. I've yet to see a decent meteor shower.

Once again the peak was cloud-covered, as were the Geminids, and Leonids. The Perseids were awesome though.

I was just outside and saw a quite slow moving meteor, possibly sporadic.
Moving West to East, just South of the Zenith, ending just South of Mars.
A bit dimmer than Capella, and mag 0.5 - 1.
Very slow moving (as expected so early in the evening?) and an obvious orange train that lingered for a few seconds, looked almost like a small firework rocket.
