(meteorobs) Observation 05/08/2003
Hi!
Glad I went out last night, it was a really wonderful pre-peak-Perseid
night with fireballs and lots of trains.
About the whom-to-send-your-reports-to issue: German reports are meant
to be sent to Juergen Rendtel, if you post them on meteorobs Rainer
Arlt will take your data from the list, it's not necessary to mail
him seperately.
Greetings
Daniel Gruen

* these are the meteors I didn't plot, either because there were
too many at a time or because they were too far from my fov;
they might as well be shower meteors

--------------------------------------------------------
enumeration starts in the 20/02/2003 session
all coordinates in mm from the lower left corner of the map
* too far from my fov to plot properly
+ comes from the Aquarid area, but that's too vague to
assign it to a radiant
~ That one was really awesome, ending with a big flash that
brightened the environment "like full moon" as I noted. I
guess this flash had about -10m, before the flash the
meteor was not that bright, maybe -4m, and it left a nice
train for about 5 seconds.
§ Two meteors from the same radiant, nearly at the same time
and with the same angle; I call such meteors "twins",
happens quite often with Perseids, at least that's what it
seems to me.
$ the time is only an estimate, I forgot to look on my watch
% this Perseid had an extremely yellow color
velocity scale:
1 - very slow; 2 - slow; 3 - medium; 4 - fast; 5 - very fast
Comments: The Perseids were simply great tonight, very
"trainy" and with Fireballs, one of which was particularily
nice, ending with a very bright flash. Kappa Cygnids are also
slowly coming up, but let's first of all look forward to the
Perseids.
Please note: d = degrees
