Chelyabinsk, beautiful black fusion crust.
The Chelyabinsk meteor was a superbolide caused by an approximately 20 m near-Earth asteroid which entered Russia's atmosphere on February 15th, 2013 at about 09:20 YEKT (03:20 UTC) with a speed of 19.16 ± 0.15 kilometres per second. (60 000 -69000 kmh. It quickly became a brilliant superbolide meteor over the southern Ural region. The light from the meteor was brighter than the Sun, visible up to 100 km away. It was observed over a wide area of the region and in neighbouring republics. Some eyewitnesses also felt intense heat from the fireball.
Due to its high velocity and shallow angle of atmospheric entry, the object exploded in an air burst over Chelyabinsk Oblast, at a height of around 29.7 km (97,000 ft). The explosion generated a bright flash, producing a hot cloud of dust and gas that penetrated to 26.2 km (16.3 mi), and many surviving small fragmentary meteorites, as well as a large shock wave. The bulk of the object's energy was absorbed by the atmosphere. The total kinetic energy before atmospheric impact estimated from infrasound and seismic measurements was equivalent to the blast yield of 400–500 kilotons of TNT, range from 26 to 33 times as much energy as that released from the atomic bomb detonated at Hiroshima.
