Hi All,
I have created a page on my Strewnify website, for the recent fall in
France:
https://www.strewnify.com/y20230213_02z_31u/
As others said, one find has been confirmed, estimated at 100 grams and
found near Saint-Pierre-le-Viger in Normany, by the Vigie Ciel / FRIPON
team.
I have very high confidence in my search area prediction, since the
trajectory was derived by two independent sources (UKMON and IAU MPC) and
the wind data is good. My simulation input data is attached. Let me know
if you have any questions.
Happy Hunting,
Jim Goodall
