'''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 [[Asteroid impact prediction|successfully predicted]], which was discovered by the [[Asteroid Terrestrial-impact Last Alert System|ATLAS]] survey. The [[Center for Near-Earth Object Studies]] reported a fireball on 10:54 ([[UTC]]).<ref name=earthsky1/>
== Discovery ==
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]].
