Re: (meteorobs) Re: Reported Fireball Magnitudes
Howdy, Ed! One possible explanation is that your meteor spectra are over a
much more limited field of view than a human observer: you might think this
would come out in the wash when doing rate comparisons, but maybe not...
After all, there are at least THREE low-population-index ('bright') meteor
showers active at this time: PERs, CAPs, and SIAs (r=2.6, 2.5, and 2.9
respectively). And in addition, the KCGs are high-r, but are also
anecdotally associated with fireballs. The result is that if there is ANY
relationship between the distance you observe from a radiant and the number
of shower members you see, this relationship will skew the results of
visual observers (with 60-100o FOVs) vs. photographs (10-50o FOVs)
significantly.
I'd agree that a fish-eye vs. visual observer study of fireball rates would
be interesting though! Thoughts from Europe?
