Comments: Freezing cold (about -5°C) combined with wind made 
it at least "uncomfortable" to lie outside, but it was nice to
see the night sky again after some really cloudy weeks since
before (oh well) the Leonids. I was counting seven stars in 
field 17, but as I saw a meteor that was obviously about half
a magnitude darker than tau PER, so I took 4.5 as lm. That's 
not a good way to determine your lm, but field counting often
didn't give me valuable results (big differences between 
different fields etc.), so maybe I'll switch to a "find the
faintest star I can still see"-method.
The Monocerotid was nice and appeared in bright white color
near Jupiter nearly down to the horizon, leaving a short
afterglowing train. It was a bit brighter than Jupiter, which
gave me a good possibility to find its magnitude.
I hope conditions stay fine for the Geminids and the possible
Ursid outburst (sounds interesting).
