Resumo

The results of an analysis of the ionospheric effects accompanying fall of the Chelyabinsk meteorite on February 15, 2013 are presented using a method of calculating the index of the disturbance of total electron content vertical variations (Wtec) according to data from the GPS receiver network. A substantial increase (by a factor of 2–3) in the Wtec index with a duration of ~1.5 h was observed in the studied region after the main height explosion accompanying the meteorite fall at 0320 UT. The ionospheric response in Wtec was most significant statistically registered at the radio rays “receiver–satellite” for the GPS located southward from the place of explosion.
