Hello,
Below you find my data of the Geminid maximum night 13/14-12-2004. Together
with a couple of friends (Sietse Dijkstra, Judith Dijkstra, Casper ter
Kuile, Carl Johannink, Michel Vandeputte, Rita Verhoef and Arnold Tukkers) I
observed this meteor stream from the top of the Kahler Asten, a mountain of
841 meters above sea level in the Sauerland region, near the city of
Winterberg. This is just east of the Netherlands in Germany. On top of this
mountain, we stayed well above the inversian layer (filled with fog, smog
and clouds up to 600 meters above sea level) which covered almost western
Europe. There we had a brilliant look on the Geminids, with limithing
magnitudes up to 6.8! We observed, depending on netto observating time and
cp , between 500 and 1100 meteors each observer! I ended up with 1003
meteors during 7.98 hours!
And what a show the Geminids put up. First we had the maximum somewhere
around 20-23 UT. Sometimes we counted up to 20 meteors within 5 minutes!
After a while , when rates slowly go down, bright Geminids appeared.
A short list of the brightest meteors:
21:23 -3 gem in Aqr
20:40 -3 Gem in Cetus
20:53 -3 Gem
22:05 -4 Gem
23:29 -3 Gem
23:56 -3 Gem
00:07 -4 gem
0:46 -4 Gem Captured with my Canon 10D and a Canon T70 both with Canon
2.8/15 mm fish eye lens
0:55 -3 Gem
1:33 -4 Gem Captured digital all sky
1:38 -4 Gem
1:39 -5 Gem Captured T70 all sky
1:40 -5 Gem Captured T70 west
2:40 -6 Gem Captured T70, shot throught Orion, brilliant picture.
2:08 -4 Gem
2:43 -5 Gem
2:46 -3 Gem
During these night I had my Canon EOS 10D with a Canon EOS 2.8/15 mm fish
eye lens end my "old" Canon T70 with a Canon FD 2.8/15 mm fishe eye pointed
in eastern and southern direction. During a quick look i found 26 Geminids
on the Kodak Elite II color slide film from the Canon T70 and about 30
meteors captured digital with the 10D camera.
These meteor pictures are not yet on the Internet. But some pictures of my
friends you'll find on the DMS website :
http://www.dmsweb.org/
So, it really was a great campaign. With many thanks to my fellow observers.
I had a great time!
