Radiation effect of the Chelyabinsk bolide

详细

A physical model of the action of radiation from a bolide on Earth’s lower ionosphere has been presented. The calculations within this model applied to the Chelyabinsk bolide on February 15, 2013, have reproduced the luminosity curves in the visible and infrared ranges in agreement with ground and satellite observations. The calculated disturbances of the lower ionosphere induced by the radiation of the bolide at the stage of the flight from an altitude of 60 to 30 km are in quantitative agreement with the results of processing of radar and satellite (GPS) observations in the Ural region.
