too many at a time; they might as well be shower meteors

enumeration starts in the 20/02/2003 session
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
* nearly on the line through NDA and SIA radiant, but closer
to NDA
+ the time is only an estimate, I forgot to look on my watch
~ it's not so clear wheather this is a NDA or a SDA
# might also be a SDA
§ traces back to a point right between CAP and NDA radiant,
it's probably Antihelion
$ thia meteor had a magnitude outburst, maybe when it broke
up into pieces
Comments: A successful observation, a little less Perseids than
yesterday, but nice ones, bright and with trains. #117 was par-
ticularily nice as it had a brightness outburst, a little flash.
This could be my last pre-Perseid plotting session, as I missed
some meteors a friend of mine who went out with me noticed while
I was staring at my star maps rather than at the stars themselves.
With one plot I even missed 3 meteors within one minute, which
is a bit frustrating. So I'll take Robert Lunsford's advice now,
and forgo plotting until mid-August.
Please note: d = degrees
