Abstract:

Energetic solar proton observations Ep approximately 300 keV in the interplanetary medium by Explorer 33 and Explorer 35 and over the polar caps by Injun 5 during the period September 1968 - March 1970 have been examined in detail. The solar proton intensities observed over the polar regions were compared to the interplanetary intensities on an absolute basis. Author
