Re: (meteorobs) -19 MagitUDE?!




     We discussed this last year but I just had another idea.  If you could
reproduce
the circumstances and set off a flash bulb at a known distance and get the
same
exposure then the flash lux rating should be similar to the meteor if it is
a similar
duration.  Knowing the distance of the flash someone should be able to
calculate an approximate magnitude.  With enough assumptions...
     Perhaps that is what you did to get the estimate?
