Abstract

This paper presents a study of the morning terminator impact on the electromagnetic signal amplitudes of VLF stations. The experimental data obtained at the Geophysical Observatory «Mikhnevo» (54.9° N, 37.7° E) in 2015 were used for the analysis. During the passage of the morning terminator, there is a sudden decrease in the signal amplitude. As a result of the study, it was established that this significant change is already observed at 15% of the track illumination.
