Research Abstract

By using an FM-CW radar system, we succeeded in detecting Pc5 range(150-600 sec.) ionospheric electric field variation which corresponded with ground magnetic oscillation. From the comparison of low-latitude ionospheric electric field and ground magnetic field variation at an equatorial station, we concluded that the ionosphere performs as a LR circuit when Pc5 range ionospheric electric field penetrates into the lower-latitude ionosphere, and the ionospheric electric field generates ground magnetic field oscillation. We also analyzed magnetic field data obtained at the geosynchronous orbit and examined local time dependence of occurrence of Pc4 range(45-150 sec.) magnetic oscillations. It seems that the Kelvin-Helmholtz instability and the upstream waves generate Pc4 range oscillations inside the magnetosphere.
