(meteorobs) Geminids 13/12/2004

[Daniel Gruen]

Hi!

My report is late - because I've been very busy the last days - and 
short - because this was an observation with my astronomy class and 
most of the time I assisted them finding their way through the stars 
- but it still was a perfect Geminid show and therefore I'll finally 
post my report.

Greetings

Daniel

Comments: The observation had been planned together with my
astronomy class at school. Unfortunately, around 20 UT 
thick fog came up from the valley, covering our sky at 320m 
altitude. As this did not change we called a restaurant in a
nearby village, 520m high and they said it was clear there -
we went there and saw a great show of more than 1 GEM per 
minute.
The official observation is short because most of the time I
spent settling down in the cold and helping the others (we
were eight observers) with their first meteor experience.
