Rrecovery and planned study of the Saint-Pierre-Le-Viger meteorite: an achievement of the FRIPON/Vigie-Ciel citizen science program

Résumé

Asteroid 2023 CX1 was discovered by Krisztián Sárneczky of Konkoly Observatory on February 12, 2023, only 7 hours before it encountered the Earth, which made it possible to track it and calculate its orbit very precisely. The potential strewnfield was determined in parallel by several groups and quickly released (e.g.: https://www.imo.net/the-atmospheric-trajectory-of-2023-cx1-and-the-possible-meteorite-strewn-field/). The FRIPON/Vigie-ciel collaboration quickly mobilized its network to set up a field search campaign. An initial team of researchers and amateur enthusiasts met on the morning of February 15 in the fall zone identified by the international teams. On the programme: information for local resident access authorizations, meetings with mayors, scouting out favorable sites, and initial field research. At 4:47 pm on February 15 the eyes of Loïs Leblanc, an 18-year-old art school student and member of the FRIPON/Vigie-Ciel team, were caught by a dark stone barely above the ground in a field located in the commune of Saint-Pierre-le-Viger (Seine Maritime), soon identified as the meteorite that we were searching for. The stone weighed 94 g and, during the following days and weeks, 10 more stones, weighing between 2 and 24 g, completed our harvest of extraterrestrial matter.
