PENETRATION OF SOLAR PROTONS TO SYNCHRONOUS ALTITUDE.
Abstract
Solar proton fluxes in two energy intervals (5-21 MeV and 21-70 MeV) were measured with detectors aboard the geostationary ATS-I satellite during the solar proton event which began on 28 January 1967. Comparison with data obtained by satellites outside the magnetosphere shows that: (a) protons with energies greater than 21 MeV have essentially free access to synchronous altitude; (b) protons in the 5-21 MeV energy interval show a diurnal variation with the flux approaching the interplanetary flux level near local midnight. The transmission efficiency of the magnetosphere is not well organized by either the local (synchronous) magnetic field or the K sub p index. (Author)
