2019 MO, temporarily designated A10eoM1, was a small, harmless 3-meter near-Earth asteroid discovered by ATLAS–MLO that impacted Earth's atmosphere on 22 June 2019 at 21:25 UT.[3][4][5][6] The impact of the bolide generated a 5-kiloton-equivalent explosion off the south coast of Puerto Rico which was detected by infrasound detectors.[5] The strewn field would be spread over the Caribbean Sea.[7]

The Apollo asteroid was inbound approaching a late July perihelion (closest approach to the Sun) when it impacted Earth at 16.1 km/s.[8]
