Results of the following trapped radiation experiments are discussed 1-4 MeV electrons as observed during the fall of 1963 on a polar satellite, with an emphasis on the changes this population is subject to even at a period of relative solar quiet 1 to 4 MeV protons obtained in a recent rocket flight near the equator up to L values of 3.7 55 MeV protons observed periodically over a period of 4 years mirroring at the South Atlantic anomaly.
