Abstract : From a much larger body of data on solar protons Ep > 0.3 MeV obtained by Explorer 35 since July 1967, the following ten events were selected for the detailed study of intensity vs time and of angular distributions of intensity in interplanetary space near the earth: November 18, 1968; August 9, 1967; May 13, 1969; January 24, 1969; March 21, 1969; June 25, 1970; January 31, 1970; July 1, 1970; November 27, 1967; and July 6, 1970. The bases of selection were that the events be of adequate intensity for statistically satisfactory study and that they be 'simple'--that is, reasonably attributable to a single solar flare so that their time histories were not complicated by overlapping emissions of particles. The principal findings for these events are discussed in the report. (Author)
