enumeration starts in the 20/02/2003 session
all coordinates in mm from the lower left corner of the map
* not sure with the shower association in this case

velocity scale:
1 - very slow; 2 - slow; 3 - medium; 4 - fast; 5 - very fast

Comments: Didn't have too much time to observe lately, but
tonight I went out. No unexpected activity, but two extremely
slow meteors within three minutes, before moonrise around
21:30 UT made observation impossible.

Please note: d = degrees
