Hi!
One last per-peak glimpse on the Perseids. I don't have much hope to
see them tonight, though, at the moment we're having more clouds than
clear skies...

enumeration starts in the 28/07/2005 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:
Wheather is very unsteady here, but this night for one it
was clear and cold (only 9d C in August!).
Clear skies to all for the Perseid maximum, here it looks
rather cloudy at the moment.
Please note: d = degrees, all times in UT
