2024 UQ, designated formerly as A11dc6D, was a one-meter meteoroid that entered 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. It was discovered by the ATLAS survey. The Center for Near-Earth Object Studies reported a fireball at 10:54 (UTC).
Discovery
{{More citation needed|date=December 2024}}
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,{{CLARIFY|REASON=WHAT ARE THESE "FIELDS"?|date=December 2024}}{{Cite news |date=2024-11-11 |title=Suitcase-sized asteroid slips past NASA's early warning system, strikes Earth hours after detection—third instance in 2024 |url=https://economictimes.indiatimes.com/news/science/a-suitcase-size-asteroid-slips-past-nasas-early-warning-system-strikes-earth-hours-after-detectionthird-instance-in-2024/articleshow/115172081.cms?from=mdr |access-date=2024-12-16 |work=The Economic Times |issn=0013-0389}} only hours later was the object reported to be moving. By then, the asteroid had already reached 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 improved, showing an impact site over the Pacific Ocean.
