Remarks

Orionid earthgrazers during the second interval. I was forced to observe during the first part of the night. A French warm front with cirrus was arriving from the south. Still good and enhanced Orionid rates.

Remarks

Meteor observations before dawn. High sporadic rates and some late Orionid activity (including a very nice -2 Orionid in the Big Dipper). I had a rain shower between interval 1 and 2. 


That's all for my Orionid campagn, a remarkable one, for this year. Now up to the Leonids!
