Abstract
The geomagnetic effects of a meteor explosion on December 19, 2014 at high latitudes over the Kola Peninsula, Russia are considered. The response of the geomagnetic field was considered based on data from the magnetometer (Loparskaya Geophysical Observatory of the Polar Geophysical Institute) and stations of the International Monitor for Auroral Geomagnetic Effects (IMAGE). It was shown that the meteor explosion caused changes in the values of the geomagnetic field components. It is assumed that the sharp changes are caused by the impact of the shock wave from the explosion on the auroral electrojets, and the subsequent wave-like variations of the components are caused by the modulation of ionospheric currents in the dynamo region of the ionosphere by acoustic-gravity waves. For the first time, it was suggested that sudden changes in the geomagnetic field are caused by the impact of the shock wave from the meteor explosion on auroral electrojets.
