Mission Name: Pioneer 5A triple coincidence omnidirectional proportional counter telescope was used to observe terrestrial trapped radiation and solar particles (protons E>75 MeV, electrons E>13 MeV). Measurements were obtained for about 2 months during which a week of quiescent magnetic field conditions followed by two geomagnetic storms closely spaced in time occurred. The date of transmission of the last useful information was May 16, 1960.
