Automated detection
MetDetect searched the KYUX radar around the fireball time. It missed the fall: its answer contains none of the hand-identified debris.
- 0of the 2 hand-identified cells on KYUX found
- 2hand-identified cells missed
- 76cells reported that were not identified by hand
MetDetect RUN-41, 29 Oct 2026. Leave one fall out: every learned part was trained without the fall it is scored on. The design falls were used to develop the method, so their scores are development results; the held-out falls were not. This fall was held out. The hand identification is the reference these numbers are graded against.
Dark flight
After the fireball goes dark, meteorites fall freely through the wind. Each radar cell is flown down to the ground through the winds of that day; the coloured areas show where stones of each mass most likely landed, and the black line runs from light to heavy stones (solid where the radar traced it, dashed where extended).
Pixel estimate, computed by P. Shober with MetDetect: winds from ERA5 (ECMWF), masses for an ordinary-chondrite density over a range of shapes. Preliminary: it does not fit the fireball itself, so the heavy end of the line is an extrapolation.
Human identification
The radar signatures of this fall were identified by hand by Marc Fries (NASA ARES, Johnson Space Center). Read the original report (archived copy).
Meteorites
Marc Fries reports ten martian meteorites (shergottites) recovered from this fall, the first martian meteorite fall in the United States. MetDetect's records list this event as Black Silver Mine.
