Abstract
Loss characteristics of inner belt electrons have been studied since the Starfish and USSR nuclear explosions in the upper atmosphere in 19621–3. The solar flares of September 2, 1966, and May 23, 1967, were the first natural events to increase the electron population above the artificial level4,5. We have studied the electron flux levels following the May 1967 event for a three month period starting in August 1967. Electron flux levels above 120 keV were monitored by ionization chambers also used as solar X-ray monitors on OGO IV in polar orbit. Supplementary electron data above 280 keV were obtained from the C1 detector on the 1963 38C satellite also in polar orbit. Details of the 1963 38C detectors have been described previously1.
