(meteorobs) Quadrantids in LA
Morning!
I got up to watch for a couple of hours as peak
approached, but after a beautiful night clouds rolled in within minutes of the
time I got set up. Clouds were all cirrus and cirrocumulus, and highly
variable --- from 20 per cent cover to one hundred per cent and back again
within a matter of minutes, repeating the cycle several times. The clouds
were quite thin, and the average limiting magnitude was about 5 throughout the
observing period, using IMO areas 3 and 9. Then everything thickened
abruptly and there was no point in going on. At least I can finally say
I've seen Quadrantids -- I don't think it's ever been even this clear this week
in previous yers!
With such poor conditions and a short teff, I
don't know how useful this will be, but here's what I've got.
