Abstract

We present the results of instrumental observations conducted during the fall and explosive destruction of the Yakutian bolide. It was shown that the bolide caused variations in the Earthʼs magnetic field with an amplitude of 5‒25 nT at distances of up to ~ 6600 km, as well as variations in the electric field in the near- surface atmosphere with an amplitude of ~100 V/m, and microbaric variations in the form of an infrasound signal propagating along an atmospheric waveguide with an amplitude of ~ 15 Pa at a distance of ~ 4500 km from the impact site.
