Saint-Symphorien, France – Saturday, March 25, 2023,12:17 AM local time, A small meteor fireball was observed heading northeast at 14 km/s, and ending at a height of 27 km above the ground. The event was measured by the FRIPON camera network, and the slow entry speed, and significant end deceleration indicate that meteorites are likely. However, the mass was low, entry angle was shallow, end height was high, and there was a strong west wind at the time of the fall. These factors made the strewn field rather long and recovery might be difficult. In the videos, it appears there were only 2 fragments, one of which was significantly larger than the other.
The trajectory provided by FRIPON was run through the StrewnLAB software to predict the search area shown below. Please download and review the Google Earth files below for detailed maps of the search area.

Weather Data
The weather data below is sourced from weather balloons, and publicly available via NOAA’s Integrated Global Radiosonde Archive (IGRA). This data is downloaded and post-processed by the StrewnLAB algorithm, to account for changing weather patterns and weather balloon drift. The plots have altitude on the y-axis, in kilometers above sea level. The wind speed below 10km has large effect onthe drift of meteorites.
There were high winds from the west at the time of the fall, causing meteorites to drift east
