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:
I had to stop the first oberserving period due to clouds,
went to bed, and out again at half past UT midnight.
Conditions were better then, and it was nice. There were
no spectacular meteors though, maybe besides a very slow
one I saw near the southern horizon before starting the
first period. Meteor #45 might not be a SAG, but as the
radiant is very diffuse and the velocity fits, I think it
was a Antihelion meteor.

Please note: d = degrees
