Radio-physical and optical effects in the magnetically conjugated region in the Araks experiment

A common oscillation period was identified for signals of a ground-based photometer at 5577 A and a radar at 44.96 MHz in the investigation of artificial auroral disturbances in the ionosphere in the magnetically conjugated region in the Araks experiment during the injection of electron pulses from the rocket. An analysis of experimental data indicates that these signals are connected with the stimulated precipitation of magnetospheric plasma under the effect of VLF or ELF waves excited in the region of electron-pulse injection.
