Re: (meteorobs) Re: photo strategies for Leonids '00?



Micheal:
    Did you note the colour of these meteors?  High velocity meteors like
the Perseids and Leonids generally have strong emmissions at the blue end of
the spectrum.  For example, strong Ca+ H&K lines just below 400.0 nm.
Perhaps this colour film is not sensitive to this region.  Did you check the
spectral characteristics of this film?  A fireball as bright as you say it
was would definitely be recorded on a panchromatic film.  For that matter,
a -10 fireball is bright enough to cast a shadow so I can't see how it would
not be photographed.  An example of a -10 fireball secured with a Sandia
All-sky camera is shown on our Bolide Detection Network home page at:

Bolide EM980814a.  Also check the link to the Woodinville Washington site
for a video clip of a fireball secured by Ajai Sehgal.  I think it is still
on his home page.
