Meteorite fragments of asteroid 2024 BX1 recovered nearby Berlin are aubrites

On January 21st, 2024, a small (meter-sized) asteroid now designated 2024 BX1 and detected while still in space entered the Earth’s atmosphere near Berlin (Germany). Fragments of the corresponding meteorite have now been found and determined (by Peter Jenniskens and team) to belong to the rare group of aubrites (enstatite achondrites). This meteorite will certainly have an associated orbit and will be added to the list as soon as both its name (from the MetBull DB) and orbit are officially announced.

Large fireball in North-Rhine-Westphalia (Germany)

On March 2nd, ca. 23:38 UTC (0:38 local, i.e., CET), a large fireball was observed over North-West Germany, as the IMO (International Meteor Organization) reports. At an estimated diameter of 2 meters and a mass of about 10 tons (although this is contingent on the assumed entry velocity of 14 km/s and the assumed density of 3000 kg m3). At that size and relatively slow velocity, it seems plausible that some meteorites survived, but again, this depends on the assumptions made. Any meteorites would have fallen to the south-east of the city of Wesel on the Rhine.

Of course, there many meteors falling all the time, but this one seems very well observed (165 observations accross multiple countries!) and also relatively large; furthermore, there are several films of the meteor captured from multiple angles – so it seems likely that in this particular case, if any meteorites are found, they will have a very well-defined orbit. We’ll see if anything interesting (in terms of meteorites, of course!) comes from this – until then, that meteor goes to the candidate list. /m4
