The year 2006 in images and words
A good year, despite the bad weather in the Netherlands. Most observations were done in southern France (holiday) and Spain (a mini expedition for the Leonids).
The Perseids and other southern summer streams were observed from southern France. I stayed there with my wife and kid in Entrecastaux (Provence). A total of 40 hours observing time resulting in 1200 meteors. Amongst them several fireballs, a -5 SDA, a -5 CAP and a -7 PER.
The Orionids showed an unexpected strong outburst. Normally the Orionid reaches a maximum ZHR of 20. This year a maximum ZHR of 60 was reached, three times higer! Just as in 1993 there were a lot of bright Orionids. But unlike 1993, when most Orionids were white/blue in color, they looked now more yellow in color.
The Leonids showed a short outburst on the night of 18/19 November with a maximum ZHR of 100. This meteor outburst was predicted in 1999 by astronomers David Asher and Robert McNaught. According to these astronomers, the earth would move trough a so called "one revolution" dusttrail of comet 55P/Tempel-Tuttle. It was left behind by the comet in 1932. So DMS organised for the last time a (mini) Leonid expedition.
I observed this outburst from a small village called Orchiva, Andalusia, Spain. There I was with my friends Jaap van t Leven, Peter Bus, Carl Johannink and Michel Vandeputte. Together with NASA astronomer Peter Jenniskens, Casper ter Kuile and Robert Haas multistation video observations were done.

Picture 6: ZHR profile based on my Leonid observations on november 19, 2006. Clearly visible is the outburst caused by the 1932 dusttrail of comet 55P/Tempel-Tuttle. The higher than normal ZHR's between 2:24-3:36 and after the main outburst is caused by the filament structure of comet 55P/Tempel-Tuttle.
