Witnesses have reported seeing a bright fireball meteor over much of the Khakassia and Krasnoyarsk republics in southern Siberia at about 6.50 pm local time on Tuesday 6 December 2016. The meteor is reported to habe flaired brightly, but with a 'cold light, like a fluorescent lamp', for three to four seconds, and that about 30 secondes after that a lound bang was heard. Natan Eysmont of the Russian Space Research Institute has suggested that this could have been caused by a small stoney asteroid 10-15 m in diameter.

A fireball is defined as a meteor (shooting star) brighter than the planet Venus. These are typically caused by pieces of rock burning up in the atmosphere, but can be the result of man-made space-junk burning up on re-entry. Objects of this size probably enter the Earth's atmosphere several times a year, though unless they do so over populated areas they are unlikely to be noticed. It is possible that this object will have produced meteorites that reached the surface (an object visible in the sky is a meteor, a rock that falls from the sky and can be physically held and examined is a meteorite) aound the Babik Valley area, accoriding to local authorities.
