November 12, 2019 02:51:45 UTC – Residents of St. Louis Missouri and surrounding areas, reported seeing a fireball on Monday night, just before 9 PM Central time. NASA released a report indicating the possibility of meteorites on the ground, which was validated soon after by the discovery of Doppler radar signatures, just southwest of Warrenton, Missouri. Please review the links below and the attached files for detailed info.

The videos shown here were used to calculate the trajectory in the StrewnLAB
A computer simulation program, written by Jim Goodall. For... bulletin, attached below.
Doppler Radar
There is some great Doppler data on this fall, please refer to Pat Branch’s Doppler Article for details…
StrewnLAB Results & Data
The attached report and additional files contain the details of the StrewnLAB trajectory simulation, and the Doppler data. I spent roughly 8 hours reviewing the video data for this event and, in the end, the extracted trajectory is similar to NASA’s early report, although slightly different. I am very confident in the results of this simulation, because the match to Doppler data is excellent.
If you plan to hunt for meteorites at this location, feel free to contact Jim Goodall and request a more detailed map.
Bulletin Version 1.1 posted. Further simulation provided a better resolution map. No trajectory changes. Labels added to the map for fragment sizes.
