* 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
* somewhere near the AUR radiant, at last; funny it left a
train for 3s although it was quite faint
velocity scale:
1 - very slow; 2 - slow; 3 - medium; 4 - fast; 5 - very fast
Comments: Two weeks before the Perseid maximum meteor nights
were really nice, two weeks after it's pretty depressing.
Of course I took a look at Mars first, this was the best
opportunity to do so for the next 300 years; I also had a
friend with me and for the first time five other observers
I didn't know (who had become interested by the
popularization about Mars in the media) came to my site and
I showed them some constellations and telescopic objects.
Anyway, when they all went to bed, I was left alone with the
meteors until clouds came and now it looks like summer's
leaving and autumn reaches for it's golden crown. No reason
to be too sad though, this was kind of the best summer I can
imagine.
I'm looking forward to the alpha-Aurigids, though there is
little chance for clear skies on the maximum night (01/09)
for me.
Please note: d = degrees
