Observations of Ring-Current Protons at Low Altitudes.
Abstract
Variable intensities of geomagnetically trapped protons with energies between 12.4 keV to 500 keV were observed during times encompassing the magnetic storms on 20 March and 24 March 1969. These proton fluxes were measured for 1.0 < L < 1.1 near the magnetic equator, at local midnight with solid-state detectors and an electrostatic analyzer on the low-altitude satellite OV1-17. The OV1-17 observations of proton intensities with E > 200 keV are in substantial agreement with similar measurements taken with the AZUR satellite and reported recently by Moritz (Zeitschrift fur Geophysik, in press 1972). Further, the lower energy proton intensities, measured with OV1-17 instrumentation, support Moritz's suggestion that the source of these low-altitude protons is the ring current.
