8:10 GMT: Oleg Malkov, an aerospace scientist at 
  Moscow State University, told Komsomolskaya Pravda
  newspaper   that the meteorite went undetected by 
  space scanners,   likely because it was coming from
  the direction of the Sun.
  "We can only register stones coming from the 
  direction of the night sky," he explained. Malkov
  confirmed that   the meteor shower in the Urals 
  was not connected to the 2012DA14 asteroid that 
  will approach Earth in a few hours.

  7:46 GMT: Ekaterinburg’s observatory has officially 
  deemed the incident a fireball meteor shower. No 
  evacuations were called for, and radiation levels 
  were determined to be normal.
