* these are the meteors I didn't plot, either because there
  were too many at a time or I didn't see and memorize them
  good enough; 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

Comments: The sky could have been clearer, but anyway, at
least I caught a glimpse of the stars again before the waning
moon rose. Still, fair rates and a nice plotting session. It
was also particularily beautiful to see the moonrise behind
the forest, it was just faint enough not to be glaring.

Please note: d = degrees
