Dust ring around Earth caused by the Chelyabinsk bolide
The Chelyabinsk bolide was detected by quite a number of satellites. The flash itself was apparently only detected by American reconnaissance satellites, whose data were used by NASA as the basis for the publication of the explosion point coordinates and the approximate estimate of the energy of the bolide. The other satellites – mainly geostationary meteorological satellites – could only detect the bolide’s trail left in the atmosphere. These included the Japanese satellite MTSAT2 (which took several photographs of the bolide’s trail at 30-minute intervals), the Russian satellite Elektron, the European satellites METEOSAT-9 and METEOSAT-10, the Chinese satellite FY-2D, and others. The published photographs of the bolide’s trail taken by these satellites only related to February 15, 2013.
