Saint‐Pierre‐le‐Viger (L5‐6) from asteroid 2023 CX₁ recovered in the Normandy, France—220 years after the historic fall of L'Aigle (L6 breccia) in the neighborhood

Abstract On February 13, 2023, a huge fireball was visible over Western Europe (fireball event 2023 CX 1 ). After the possible strewn field calculated, first of several recovered samples, with mass about 100 g, discovered just 2 days after on ground village Saint‐Pierre‐le‐Viger. Meanwhile, more than 60 samples total kg were and piece one these is studied here. The fall occurred 220 years historic meteorite L'Aigle April 26, 1803, <120 km south. closest to Saint‐Pierre‐le‐Viger belongs same chondrite group. Both meteorites are breccias containing only clasts high metamorphic degree (type 5 type 6). Since 20% L chondrites this coincidence remarkable. As mentioned, both from rocks in work ordinary consist equilibrated recrystallized lithologies petrologic 6. brecciated texture L'Aigle, resulting remarkable light–dark structure, pronounced features Saint‐Pierre‐le‐Viger, which also fragments have been reported. compositions low‐Ca pyroxene olivine grains (Fs 21.2 Fa 23.4 , respectively) clearly require an L‐group classification. classified as L6 breccia past, has now confirmed by new data 20.7 23.8 respectively). contains local thin shock veins, moderately shocked. Most olivines planar fractures, but estimated abundance mosaicized 30%–40% among large S4 Oxygen isotope bulk chemical certainly support Bulk spectral dominated silicate minerals, that is, Fe‐bearing pyroxene, olivine, plagioclase. Isotopic, chemical, shown for comparison very similar, providing additional circumstantial evidence Saint‐Pierre‐le‐Viger's chondritic nature.
