(meteorobs) Meteor Hunt of December 26/27, 2002
December 28, 2002
Greetings Meteor Enthusiasts!
Finally, a clear night! There hasn't been any clear
nights here in a long time. It wasn't perfect though,
actually quite far from it! Fast moving clouds made
observing difficult and recording the sky conditions
likewise. A haze popped in and out with the clouds,
crippling the LM in my field of view. It was a haze
that did not blot out all the stars, though. I did not
record the LM using the star areas during those times
for fear I might alter the mean LM for the
observations, and give a wrong impression of the
results since the haze did not persist all the time.
I had a slight question about listing meteor #2 in the
report as it did seem quite fast, but I think it is
fair to say that it probably was one, which my senses
seemed to indicate at the time of the sighting.
Like always, feel free to inform me of any comments or
errors in the following report.

1. The meteor time should hopefully be off by no more
than a few seconds at most.
2. SPO = sporadics.
3. Per. = Perseus; Cam. = Camelopardalis; Tau.=
Taurus; etc.
Slow, frosty Quadrantids!
