I'm french from French Meteor Observing Network (REFORME) we are visual, radio and video observer.
I manage two video stations: an all sky camera at Cerilly and a standard FOV camera at Nancy (http://france.allsky.camera.free.fr/index_en.html)
Since this year we, videos observers, build a french meteor database http://boam.fr to group our detections.
And we discuss about our captures on more large sky observers forum http://allskycamfrance.frenchboard.com
I'm happy to see your records on your active forum, thank you

What do you think about my capture? it's my second time TLE records and I'm not experienced to reconize this detection.
It was far from my camera but I think it was a very active storm
