The year in images and words
This year I moved from Harderwijk to Ermelo. In the backyard of my new house it was dark enough to do meteor observations. Especially the lightpollution was less intense. In the period from July 1996 until January 2002 , I had many meteor watches from my backyard.
At first it seemed that 1996 would be a bad year for meteor observations. The highlight of the spring was comet C/1996 B2 Hyaktuake. In the crisp night of 27 to 28 March ( 6.9 lm ) I saw from Biddinghuizen Comet C/1996 B2 Hyakutake near the North Star with a tail of over 70 degrees.

The Perseid campaign suffered heavely from poor weather conditions. A crash action to East Germany failed, so we stayed in a cloudy Berlin when the Perseids showed an outburst.

Luckily we had a successful crash action (= desperate attempt to find clear weather) with the Leonids. After a hectic ride we observed the Leonid outburst from Woignarue, a little village in northwestern France. For several long spells we saw great activity of the Leonid fireball and a momentary peak of faint meteors. The bright meteors came from the filament structure, de weak meteors possibly belonging to an dusttrail. However, in 1996 there were no dusttrails near earth's orbit, so the cause of this structure is not known.
The whole period of the Geminids it was cloudy, only the night of December 13/4 was clear. And what a wonderful night it was! I saw more than 1000 meteors with at the end of the night the bright stuff, including a Geminide of magnitude -8. This is the most successful single night from Biddinghuizen (1994-2002).
