Thank you.I was just at the camera site in Tucson. Yes the azimuth does match
up with the Mexico trajectory. Michael Farmer

Here is what I was able to find from Dr. Fries information:
- An image from the GOES 16 GLM which shows the bolide over Mexico.
- Brief animation from NOAA weather radar from the KEPZ radar El Paso, NM.
It shows the rapidly spreading circular feature Dr. Fries describes.

The video form Tucson should make a mexico landing impossible. The fixed camera
is pointing south east and angled north east. The rock comes from the right and
crosses the rincón mountains. How is a Mexico trajectory possible? Only
possible direction based on that camera view is north to north east.

There was a daytime bolide over the AZ/NM/Mexico area this morning (16 Oct
2021) at 1323 UTC which may have generated a meteorite fall. The American
Meteor Society is reporting it here:
https://fireball.amsmeteors.org/members/imo_view/event/2021/6611
At the time of this writing, the AMS is reporting a ground track just east of
Tucson. This event shows up clearly on both the GOES East and West satellite
data, in the Geostationary Lightning Mapper (GLM) imagery, but with a ground
track that appears to be farther to the SE and in northern Mexico.
NOAA weather radar imagery from the KEPZ radar (El Paso, TX) reveals a striking
feature which appears near the location suggested by GLM and at the time
reported by GLM and eyewitness accounts. This feature is a rapidly-spreading
circular feature centered on:
107.9987°W 30.7232°N
This feature appears as an expanding circle at low altitude, moving at 30 mph
outward in all directions following the time of the bolide. This circular
signature may be birds scared into flight by the sonic boom. This same bird
feature is visible in radar data for the Monahans and Indian Butte meteorite
falls. No falling meteorites are obvious, but the event occurred at long range
from the radar and the weak radar signatures of falling meteorites may not
appear.
In summary, GLM, eyewitness, and weather radar data indicate that a meteorite
fall may have occurred in Mexico near the coordinates listed above. This site
is populated and features a few farming communities, with the "El Chocolate"
dry lake bed to its south. Conditions should be good for recovery of
meteorites. Analysis of radar data will continue.
Cheers,
Marc Fries
