Re: (meteorobs) meteor photos
Casper,
Greetings and congratulations on your crash-teams' efforts. You
certainly have the advantage being on the mainland, with many fast
roads (unless the French drivers, farmers etc. decide to protest)
being to drive to find the clear skies. I suppose there is some
'scope in the UK, and once the Chunnel is re-opened that could be used
too, but it's expensive to do it often.

Note that I was talking specifically about photographing _trains_
images and spectra.

Thanks. I have your page in my meteor bookmarks. I had a look, but I
didn't locate any '96 Leonid images. A bit early I guess. Given the
preponderance of very persistent trains at Leonid maximum, I think it
would be a great project to have a spare camera (or two) with a
grating ready to capture some Leonid train spectra. The grating needs
to be adjustable to give dispersion perpendicular to the train. These
days it may be better to capture and/or process the data digitally. So
one could take a series of images as the train distorted,
geometrically correct the train to be linear (and hence the spectrum),
which could be coadded along the direction of motion to give a decent
signal-to-noise.
All the best to you and your heroic teams (even Jacob (-:, remember
the thunderstorm at the Puimichel IMC and my car).
Clear skies for the Geminids,
Malcolm
