An image of the object was also taken shortly after it entered the atmosphere by the weather satellite Meteosat 9. According to eyewitnesses, the bolide appeared brighter than the sun, as was later confirmed by NASA.

The event began at 09:20:21 Yekaterinburg time, several minutes after sunrise in Chelyabinsk, and minutes before sunrise in Yekaterinburg. Some eyewitnesses claim they felt intense heat from the fireball. Amateur videos showed a fireball streaking across the sky and a loud boom several minutes afterwards. Local residents witnessed extremely bright burning objects in the sky in Chelyabinsk, Kurgan, Sverdlovsk, Tyumen, and Orenburg Oblasts, the Republic of Bashkortostan, and in neighbouring regions in Kazakhstan, when the asteroid entered the Earth's atmosphere over Russia. The earlier-predicted and well-publicized close approach of a larger asteroid on the same day, the roughly 30В m (98В ft) 367943 Duende, occurred about 16 hours later the very different orbits of the two objects showed they were unrelated to each other.Д¬omparison of possible sizes of the Chelyabinsk (CM mark) and Tunguska meteoroids to the Eiffel Tower and the Empire State Building. The Chelyabinsk meteor is also the only meteor confirmed to have resulted in many injuries. With an estimated initial mass of about 12,000вЂ“13,000 tonnes (13,000вЂ“14,000 short tons), and measuring about 20В m (66В ft) in diameter, it is the largest known natural object to have entered Earth's atmosphere since the 1908 Tunguska event, which destroyed a wide, remote, forested, and very sparsely populated area of Siberia. Some 7,200 buildings in six cities across the region were damaged by the explosion's shock wave, and authorities scrambled to help repair the structures in sub-freezing temperatures. All of the injuries were due to indirect effects rather than the meteor itself, mainly from broken glass from windows that were blown in when the shock wave arrived, minutes after the superbolide's flash. Its explosion created panic among local residents, and about 1,500 people were injured seriously enough to seek medical treatment.

The object approached Earth undetected before its atmospheric entry, in part because its radiant (source direction) was close to the Sun. The bulk of the object's energy was absorbed by the atmosphere, creating a large shock wave with a total kinetic energy before atmospheric impact estimated from infrasound and seismic measurements to be equivalent to the blast yield of 400вЂ“500 kilotons of TNT (about 1.4вЂ“1.8 PJ) range вЂ“ 26 to 33 times as much energy as that released from the atomic bomb detonated at Hiroshima, and the rough equivalent in energy output to the former Soviet Union's own mid-August 1953 initial attempt at a thermonuclear device. The explosion generated a bright flash, producing a hot cloud of dust and gas that penetrated to 26.2В km (16.3В mi), and many surviving small fragmentary meteorites. The object exploded in a meteor air burst over Chelyabinsk Oblast, at a height of around 29.7В km (18.5В mi 97,000В ft). Some eyewitnesses also felt intense heat from the fireball. It was observed over a wide area of the region and in neighbouring republics. The light from the meteor was briefly brighter than the Sun, visible up to 100В km (62В mi) away. It was caused by an approximately 20В m (66В ft) near-Earth asteroid that entered the atmosphere at a shallow 18.3 В± 0.4 degree angle with a speed relative to Earth of 19.16 В± 0.15В kilometres per second (69,000В km/h or 42,900В mph). The Chelyabinsk meteor was a superbolide that entered Earth's atmosphere over the southern Ural region in Russia on 15 February 2013 at about 09:20 YEKT (03:20 UTC).
