(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
