The year 1999 in images and words
A bad year for meteor observations. Many campaigns perished in rain or clouds. The Perseids campaign at Biddinghuizen gave only a partially clear night 12/13 August. On August 11 , I witnessed the total solar eclipse over northwestern France together with Casper ter Kuile and Marco Langbroek.
Highlight this year was the successful Leonid action at southern France and Spain.
After a 600 km drive to escape bad weather near our location in southern France, we ended up near Xalos, Spain and observed the meteor storm. The maximum ZHR was around 3600, with minute counts of the Leonids up to 47! Sometimes I counted 5 or 6 Leonids in one second, followed by a brief period with nothing. During the hour around the maximum I counted almost 1200 meteors! In total, I saw that night in 2116 meteors, a record until then. This Leonid storm was caused by a combination of the filament structure and a dusttrail of comet 55P/Tempel-Tuttle from 1899 and possibly some minor activity of the 1932 dusttrail.
The Canon T70 with standard lens captured 120 Leonids on color slide film. These pictures can be viewed here. A report of this action can be read here.

Picture 2: Leonid meteor storm on 18 november 1999 at 2:00 UT: on the original image are 27 Leonids visible. The camera made a recording of 10 minutes on Kodak Elite II color slide film.


Picture 3: About one hour before the storm peak activity was much lower.
