Abstract
The results of instrumental observations of acoustic oscillations and geomagnetic variations during the bolide-fall event on April 19, 2023 in the region of Kyiv (Ukraine) are presented. It is shown that the bolide explosion was accompanied by an acoustic signal recorded at a great distance from the epicenter of the event (~755 km) and was manifested in variations in the magnetic field. According to acoustic observations, four explosions of the largest fragments of the bolide were recorded. The total energy of the event was 4.2 × 1011 J, which corresponds to about 0.1 kt in trinitrotoluene (TNT) equivalent. The maximum amplitude of geomagnetic variations caused by the bolide explosion at distances in the range of 454–909 km was 2.5 to 4 nT.
