(meteorobs) Meteor Observations Of 5/6 October 1999



Greeting List Members

After one skipped night 4/5, not due to cloud but other commitments I
managed to get out again for a couple of hours under not very good skies
with slight haze or something that kept the limiting magnitude pretty poor
(not that is very good around home most of the time anyway). The watch
started off very well with two -2 magnitude meteors in the first 20 minutes
of the watch but after that it calmed down a bit but still it wasn't a bad
watch after all. Here are my observations for the 5/6 October 1999.

Cheers

David

REMARKS:
Air very still with slight haze present all of the time, hence the low
limiting magnitude. Pervasive local light pollution with low pressure
Sodium lighting. (W = WHITE AND OR = ORANGE)
