Hi!

The report is a little late (and it's not much to report anyway), but 
I went out Monday evening.

Greetings

+ I'll label the ones I'm sure with as NTA resp. STA, others
  as TAU
~ estimated with r=3.0, deltalm=0.0 and est. radiant height
Leonid radiant was still below the horizon at that time

 * these trains persisted only for a few tenth of a second
I will try to include a better train report from like
http://www.uraniadot be/meteors/trainform.txt as suggested
by Geert Barentsen, but I find estimating train magnitudes
quite difficult.

all coordinates in mm from the lower left corner of the map
velocity scale:
1 - very slow; 2 - slow; 3 - medium; 4 - fast; 5 - very fast

Comments: Probably one would call this hour a wasted one,
given that only three meteors decided to show up. It was
still earlier evening, so this is nothing unexpected, but
school (at 7:30 MET = 6:30 UT) really keeps me from doing
some post-midnight observations. But anyway, a nice view
of the night sky (especially in November, when usually all
you see is clouds) is a wonderful way to spend your evening.

Please note: d = degrees, all times in UT
