Abstract : The authors measure the energy spectra of high energy trapped protons utilizing nuclear emulsions exposed on low altitude polar orbiting satellites. The spectra are compared with those obtained by Heckman and Nakano (1969) at solar minimum and the effects of solar cycle atmospheric density changes are evaluated. (Author)
