We analyzed some variations in MF radio noise intensities as well as in the parameters of wave disturbances during the period when the solar eclipse (SE) occurred and during daytime periods without a SE. A factor of up to four decrease in the radio noise intensity observed during the SE was probably caused by global-scale magnetospheric electron precipitation induced by the SE. Our estimates of precipitating particle flux parameters are presented. The amplification of wave disturbances with periods from 8 to 50‒55 minutes and relative amplitudes from 0.02 to 0.04 is shown to take place during the SE.
