Abstract:

Precipitating protons with energies characteristic of the storm-time ring current were measured during all phases of magnetic activity near the low-altitude trapping boundary at midnight. The objective of this study was to examine the energy dependence of the precipitating fluxes as a function of latitude or L shell and relative to the plasmapause and the low-energy isotropic electron enhancements which are associated with the outer-zone boundary. The low-energy measurements, taken by the OV1-17 satellite, covered the timer period from 19 March-3 April 1969. Data, provided by the OV1-19 spacecraft during the same time period, were used to extend the measurements to higher energies and to examine pitch-angle distributions. Modified author abstract
