Re: (meteorobs) -19 MagitUDE?!

miller>> 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?

I thought of doing something like this myself a few months ago, but one of
the major problems I had to consider was the fact that the observatory is
about 15 feet above ground. The fireball occurred high up, but off somewhat
to one side. Somehow I would have to make the test flash from above and away
from the observatory. I really don't have any way of suspending myself or a
flash unit at suitable angles that high up...without treading air. I perhaps
could attach a camera and flash unit at the end of a stick....but to tell the
truth, I think it would be more hassle than what I'd really want to put
myself thru. I also don't think any real gains would be made in the long run.
Thanks for the idea though.
