* these are the meteors I didn't plot, either because there were
too many at a time or because they were too far from my fov or
because I forwent plotting;
they might as well be shower meteors

Meteor Data (only the two plotted Sporadics):
(caution: I changed the order of the coordinates from
XBeg-YBeg-XEnd-YEnd to XBeg-XEnd-YBeg-YEnd because I can
enter the figures faster this way; if it causes extra work
for the archievers, please tell me)

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: Seems like there is a little peak at 0:08UT, but it
looked more dramatic with the 10m-bins in my quick report
yesterday. You can see a decrease in bright and trainy meteors
in the later periods.
Please note: d = degrees
