Re: (meteorobs) Nov. 12/13 Summary
In a message dated 96-11-13 05:43:51 EST, you write:
<< was able to observe this morning under clear skies for 3.40 hours
beginning at 0600 UT. The highlight of the morning came at 0744 UT when I
recorded my brightest fireball ever. This sporadic appeared almost due east
at approximately 25o in altitude and began as -9.0 but about midway along
its path, flared to -11. Color alternated from yellow to green and back to
yellow. I immediately froze all of my movement to listen for any possible
sounds and was rewarded 11 to 12 seconds later with one short, faint "boom,"
my first ever recorded sound. A complete report will be sent to FIDAC as
soon as possible.

Judging by the short time of 11 or 12 seconds from meteor sighting to booming
noise...the meteor had to be very close to you somewhere along it's
trajectory(about 2 miles). Right off hand, if the meteor came that close to
you, I'd expect a possible louder sonic boom.... unless the meteoroid was too
small to produce much of a noise. My guess is that this shouldn't diminish
the appeared magnitudes any or at least not by much. Can't wait to see
another fireball of that kind of magnitudes myself...dot it's been a long time.
