Abstract
According to the observations of VLF radiation in Kamchatka for the period from 1997 to 2017, radiation envelope periodograms at the frequencies of 0.7, 1.2, 5.3 kHz were obtained. The period of 1440 min was determined. It is caused by the Earth rotation around its axis relatively the Sun. Another period of 1436 min was also distinguished. It coincides with the Earth diurnal rotation relatively remote stars. The cause of the maxima occurrences at these periods may be the X-radiation of the Sun and the Galaxy. It was shown that VLF radiation intensity in the period range from 0.1 to 1000 days increases proportionally to the period logarithm and that the main and higher harmonics of diurnal frequency are observed in the radiation envelope spectra.
