Hi!

Here's my report from last night. 

Robert, I do think the new table at the end of the outlook is very 
handy, so keep up the good work!

Clear skies

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

* couldn't plot
+ not completely sure with shower association, a nice 
  nearly-earthgrazer

Comments: Nice conditions; #382 was quite a nice one, crossing
maybe 45 degrees of sky and leaving a train for 2 seconds. Tonight
there'll be "The long night of the stars" at our local astronomy
group, hope some people'll come and have a look.

Please note: d = degrees, all times in UT
