enumeration starts in the 02/01/2004 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
* this one fits the radiant in Coma Berenices
Comments: Clear skies, but surprisingly not so cold, maybe
because there were clouds coming in at the end of the observation.
Not much to report, the radiant in central COM could be active
or not, but I encourage everybody to go out and watch for the
possible maximum tonight or tomorrow.
Please note: d = degrees, all times in UT
