(meteorobs) RE: meteorobs-digest V3 #146
Hi again list members,
I managed to get another watch in last night after the clouds had let go
and the moon had set (moonset is about 22:10 local time) but the clouds
didn't let go until about 23:15 local time. In the end I went out for only
an hour and a half as the skies were not good with a pervasive haze giving
quite poor sky conditions (LM about 5.0). Hopefully I can get out before
dawn later on in the week to see if I can catch some Orionids.
Anyway here are the results of last nights watch for what they are worth.
Cheers and clear skies to everyone.

REMARKS:
Pervasive local light pollution with low pressure Sodium lighting.
Fairly pervasive thin haze giving the very poor sky especially when
this is exaserbated with the local orange light pollution. Quite warm
with little or no wind. (W = WHITE AND OR = ORANGE)
METEOR 1 - PROJECTING THIS BACKWARDS INTERSECTS THE STA RADIANT BUT THE
PATH LENGTH APPEARS TOO SHORT FOR THE DISTANCE FROM THE RADIANT
THIS IS WHY IT HAS BEEN ASSIGNED SPORADIC RATHER THAN AN NTA.
