On February 15, 2013, a 10,000 ton meteoroid entered the Earth's atmosphere over Russia at about 09:20 YEKT (03:20 UTC). It passed over the southern Ural region and exploded in an air burst over Chelyabinsk Oblast. About 1,500 people were reported injured, including 311 children. Health officials said 112 people had been hospitalized, mainly from injuries caused by glass from windows shattered by a shock wave; two were reported to be in serious condition. As many as 3,000 buildings in six cities across the region were damaged by the explosion and impacts. The meteor created a dazzling light as it air burst, bright enough to cast shadows during broad daylight in Chelyabinsk.
