Sarneczky on CCD images obtained on Jan. 20.9 UT with the 0.6-m Schmidt telescope at Piszkesteto, Hungary, apparently impacted the earth's atmosphere and was photographed as a bright fireball over Berlin, Germany, about 2.7 hours after discovery (or 2024 Jan. 21.022 UT). Attempts to find any meteorites are underway, aided by extensive photographic records of the fireball across north-central Europe (see the American Meteor Society's website URL https://fireball.amsmeteors.org/members/imo_view/event/2024/423). The object was designated 2024 BX_1 on MPEC 2024-B76. P. Veres (Minor Planet Center) writes that he received prediction announcements of an impact over Germany from the Scout system of the "Center for Near Earth Object Studies" (JPL) and from the European Space Agency's Meerkat system. This would be the eighth asteroidal object discovered from ground-based telescopes prior to impacting the earth's atmosphere (cf. CBETs 5221, 5230).
