* 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
* not absolutely clearly a NDA, rather a Antihelion meteor
+ could be a Perseid also, but AUR seems more probable in
this case
~ very nice because it seemed to be glittering
velocity scale:
1 - very slow; 2 - slow; 3 - medium; 4 - fast; 5 - very fast
Comments: The total lack of bright meteors didn't make this
a sad observation as I was simply astonished by the marvellous
sky with the milky way as clear as I've never seen it before
from my site, I think. Simply wonderful.
Please note: d = degrees
