Howdy all
We've had a bunch of fireballs with dozens of AMS eyewitness
reports over the last couple of months. In going back over them I found a
really nice one that escaped my notice:
https://fireball.amsmeteors.org/members/imo_view/event/2022/740
The videos of this event show an exceptionally long-lasting
fireball (~14s) with pronounced fragmentation. It appears that multiple
objects slow down towards the end of the fireball. This appears to be a good
candidate for a meteorite fall.
Searching the radar data yielded some interesting signatures
~35km NW of Fredricksburg, TX on the KGRK, KEWX, KDYX, and KSJT radars. None
are especially strong but they seem to cluster. I cannot find any pronounced
surface features, windmill farms, radio towers, or other reflectors at this
site. I will draw up a NASA Meteorite Falls page for this event and share
images once I'm happy with the data refinement. In the meanwhile, could y'all
have a look? This one may be promising. There is a signature on KSJT in the
1.49 degree sweep, 0602 data set, which appears only 40s after the fireball
terminus. Jormungandr calculates that it corresponds to a/an 11.1kg
meteorite(s).
Cheers,
Marc Fries
