2024 UQ, designated formerly as A11dc6D, was a one-meter meteoroid that struck the Earth's atmosphere and burned up harmlessly on 22 October 2024 above the Pacific Ocean off the coast of California. 2024 UQ is the tenth impact event that was successfully predicted, which was discovered by the ATLAS survey. The Center for Near-Earth Object Studies reported a fireball on 10:54 (UTC).
The Asteroid Terrestrial-impact Last Alert System (ATLAS) first noted this asteroid. Due to 2024 UQ being close to the boundary between two adjacent fields, only hours later was the object reported to be moving. By then, the asteroid had already impacted Earth. After prediscovery images identified from the Catalina Sky Survey and a flash recorded from the meteorological Geostationary Operational Environmental Satellite (GOES) satellite, the impact trajectory was much better defined, showing the impact site over the Pacific Ocean.
