Abstract
Proton flux maps of near-Earth space are presented using the Proton Telescope (PROTEL) detector on CRRES. The proton energy range covered is 1 - 100 MeV. Contamination of PROTEL measurements due to > 100 MeV protons is corrected using loss cone data, resulting in consistency with dosimeter measurements and a Monte Carlo computer model of PROTEL. Two states of the inner magnetosphere were found during the CRRES mission, a quiet state having a single proton belt, and an active state with a double belt. The properties of the new population in the second belt are presented. Comparisons with NASA proton codes are made.
