Abstract : The particle measurements by the P78-2 SCATHA satellite at near geosynchronous altitudes have been analyzed to obtain average electron and proton fluxes in the energy range 87 eV to 288 keV. The variation of the fluxes about the average values is also reported and the average fluxes are compared to those measured during an intense spacecraft charging event on September 22, 1982. These calculations provide a representation of the plasma environment, which can be used to quantify the surface charging of spacecraft materials in geosynchronous orbit.
