(meteorobs) Observation 23/04/2003
Hi!
After being clouded out on the Lyrid maximum, I went out last night to
see wheather there is some activity left, but I still can't really
tell (only a very queationable Lyrid appeared). But it was nice
because activity after local midnight was at least fair and it wasn't
so cold.
Greetings
Daniel Gruen

enumeration starts in the 20/02/2003 session
all coordinates in mm from the lower left corner of the map
* #40 came from out of map 2, so I only plotted the part that
was in map 2 (therefore XBeg and YBeg aren't correct)
velocity scale:
1 - very slow; 2 - slow; 3 - medium; 4 - fast; 5 - very fast
Comments:
The first 1.5 hours were very quiet, but after that it was quite
a nice evening. The only Lyrid seen was swift and faint and the
plot didn't exactly cross the radiant, but as it was plotted with
low accuracy, I guess it was a Lyrid.
