* 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;
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
* I did plot these meteors, but I didn't measure the plots
as I could clearly associate them with a known shower;
If anyone finds it worthwhile to still do so, please mail
me and I won't hesitate
velocity scale:
1 - very slow; 2 - slow; 3 - medium; 4 - fast; 5 - very fast
Comments: There were no meteors I can still remember
anything special about - maybe because I'm suffering
from a lack of sleep now, having observed 5 nights in
a row. I hope the 6th night will follow!
Please note: d = degrees
