2024 BX1, previously known under its temporary designation Sar2736, was a metre-sized asteroid or meteoroid that entered Earth's atmosphere on 21 January 2024 00:33 UTC and disintegrated as a meteor over Berlin.[2] It was discovered less than three hours before impact by Hungarian astronomer Krisztián Sárneczky at Konkoly Observatory's Piszkéstető Station in the Mátra Mountains, Hungary.[2] The fireball was observed by the cameras of the AllSky7[4] and Fripon[5] networks. 2024 BX1 is the eighth asteroid discovered before impacting Earth, and is Sárneczky's third discovery of an impacting asteroid. Before it impacted, 2024 BX1 was a near-Earth asteroid on an Earth-crossing Apollo-type orbit.
