On the 15th February 2012 a big meteor burned up over the Russian city of Chelyabinsk, which is east of the Ural mountains. Many people reported the incident and you can see several video recordings that have been uploaded on the internet. The meteor lit up and turned into a great bright fireball in the sky. The sonic boom from the fireball set off car alarms and shattered windows and doors. More than 1200 people were injured.
The Russian president Putin now demands a new early warning system for meteors. Experts say the meteor was to small to be detected.
