Abstract

We considered the issue of an anomalous decrease in the amplitude of the magnetic field components of the VLF transmitter signals at the Lovozero station (LOZ) during geomagnetic disturbances at night to daytime values. During this period, auroral precipitation was observed at LOZ, and riometer absorption was recorded at Sodankyla and Ivalo. According to POES satellite data, electron precipitation with particles energies >612 keV was observed in the region of the Lovozero station. The scale of the projection of the precipitation area for particles with energies >287 keV averaged about 200 km. Using numerical modeling, shown that the experimentally observed effect of the nighttime decrease in the amplitudes of the VLF transmitter signal can be explained by the existence of an inhomogeneity in the ionosphere caused by a flux of electrons with energies >200 keV and scales of inhomogeneity about 200 km.
