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

* Doesn't fit any on the Aquarid radiants perfectly, so I'll just
  call it Antihelion
+ a nice one very near to the radiant

Comments: School's out for summer - and I have time for 
observations. Now last night it was nice with the sky being
quite clear and many showers showing some activity. The 
Perseids seem a little inert yet, but we'll wait and hope-
fully see.

Please note: d = degrees, all times in UT
