Atmospheric effects caused by the fall of the Izhevsk bolide on November 17, 2021

Abstract

Using the results of instrumental observations, the acoustic, electrical and magnetic effects of the explosive destruction of the bolide on November 17, 2021 in the region of Izhevsk was established. It was found that the effects are non-local in nature and were registered at a significant epicentral distances from the explosion. It is noted that variations in the magnetic field were observed both during the fall of the bolide and during the arrival of the atmospheric signal at the registration point. Based on the characteristic frequency of the atmospheric signal, the bolide explosion energy was estimated, which was 9.4•1010 J.
