Dear Everyone,
Below my VISUAL RESULTS for last night (19/20 august 1996). We have had a
splendid night at our dark site Biddinghuizen (the Netherlands, 52d 29'16"
N, 5d. 41' 19" E), with clear, very dark skies (Lm +6.8 to +6.9) and lots of
meteors, though most faint ones. In 4.63h effective between 20:45-02:45 UT I
observed 127 meteors of which 105 sporadics, 17 late Perseids and only 5
Cygnids. All meteors have been plotted on a gnomonic map.
A multistation photographic campaign was conducted this night between us
(Biddinghuizen: Casper, Koen Miskotte and me) and Varsseveld (Hans Betlem
c.s.). Though there weren't that many bright meteors, we expect some
multistation meteors to be photographed.
Brightest meteor was a -3 Cygnid that appeared at 22:58:29 UT, distinct blue
colour with 1.5 sec. persistent train. Another very nice meteor was a long
and slooooooooooooow one (sporadic) that appeared at 22:08:58 UT, brightness
about -1 and again distinctly blue, short persistent train (0.5 secs.). It
took several seconds, and travelled from southern Aquarius into the
Pegasus-Andromeda border area. I was plotting a meteor at that moment, Koen
shouted, I looked up and saw at least 1.5-2 seconds of the meteor!
Below my data. Data of Koen Miskotte will follow later this day.

PS: coming nights will be bad in the Netherlands: thunderstorms. But maybe
coming weekend some work might be possible, though moonlight will start to
interfere.
