Hi Marc - welcome back! This fall also appeared on Pocatello, Idaho radar. Over
a dozen meteorites have been recovered to date, some weighing over 400 grams.
From cut surfaces, it appears to be an ordinary chondrite - perhaps H5 or H6.

Subject: EXTERNAL: [meteorite-list] Much-delayed notice of UT meteorite fall
I have been on international travel for almost two weeks, and the loaner
computer I was using "bricked". I've been without a computer or email for
almost two weeks as a result. On 15 August I sent an email to the List from my
phone to try to get the word out, but that apparently didn't work. Here's the
original email again, and now that I'm back in the States with a working
computer I'll generate a strewn field for the Salt Lake City fall ASAP.
Cheers,
Marc Fries

Greetings
I am on international travel with a bricked computer and am trying to get
word out about a possible Utah meteorite fall. This was a daytime bolide of 13
August. I will have difficulty working on this event until I return stateside
in almost two weeks, so others need to jump in and check this event.
Radar signatures appear in higher elevations of the KMTX 1428 radar data
set. They are mostly visible in the Velocity data because the radar is nearby
and there is interference from ground clutter and weather. They appear roughly
parallel to and north of I-80 along a track that approximately matches both the
AMS ground track and GLM signatures. The ground track of these radar signatures
is long, but that appears to match GLM data showing a low entry angle, fairly
long ground track. I see signatures consistent with fast-moving meteorites in
five radar sweeps (between 4 and 12.4 degree sweeps).
Videos of this event show a fast moving, bright daytime fireball. I'm
surprised to see radar signatures given the apparent speed, but they appear
reasonable for a meteorite fall. The ground track is partially over the Great
Salt Lake and partially over shoreline not far north of I-80.
