The year 2004 in images and words
A difficult year, just a few observations due to bad weather. A partially clear night 17/18 november I had to pass due to the flu. Fortunately, I could observe the Perseid outburst of 11/12 august and the Geminid maximum so the year 2004 ended on a positive note.
In the period August 9 to 13, I teamed up with Carl Johannink, Rita Verhoef and Romke Schievink. We made the German highways unsafe to look for the best possible start position to drive to clear weather for the expected Perseid outburst. We ended up in the village Britzingen where we witnessed a short burst of faint meteors (caused by a dusttrail from comet 103P/Swift Tuttle from 1862, 1 revolution) and afterwards an increase of bright meteors (possibly the filament structure of comet 103P/Tempel-Tuttle, the same structure that caused the strong Perseid outburst of august 12, 1993).

The Geminids 2004 were a huge succes. In the Netherlands we suffered from an inversion layer under an area of high pressure. We drove to the highest mountain in the Sauerland region of Germany called the Kahler Asten. There we could observe the Geminid maximum hundred meters above the inversion layer under crystal clear skies. During 8 hours of observations I counted 1003 meteors, including a bunch of nice fireballs.
