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
Comments: Now, is it worth it to go observing on a more or
less clear night in late February? While the answer for most
people would probably be "no", for those who only need to
see the firmament above and have time to contemplate a little
to be delighted - what else can you ask for?
Who am I to criticize the fact that only two meteors made this
an actual _meteor_ observation... better times will come.
Please note: d = degrees, all times in UT
