1999 has been my best year so far for Geminids, despite less than ideal skies on the peak night. Here's the count:

Total count 113.

There were many bright Geminids, among them two spectacular fireballs of magnitude -5 or so. As opposed to comparable Leonid fireballs, these fireballs left trails lasting only a few seconds. I also noticed a highr proportion of bright Geminids on the 14/15 night. All in all, an excellent observation campaign, considering I stayed at home the whole time. As many readers of this group already know, its hard to beat a hot tub for this kind of of work!
