Abstract : Several recent observations of low-energy proton and electron intensities within the energy range of about 100 eV to 50 keV in the eath's radiation zones with a sensitive array of electrostatic analyzers borne on the earth-satellite OGO 3 during mid-1966 are summarized. Measurements of charged particles of the extraterrestrial ring current during a moderate geomagnetic storm, of the low-energy proton and electron distributions in the vicinity of the midnight 'trapping boundary' near the magnetic equatorial plane, and of upper limits for proton and ion (100 eV = or < E/Q = or < 50 keV) energy fluxes deep within the innder radiation zone are presented together with several introductory comments concerning the morphology of the omnidirectional intensities of energetic electrons (E = or > 40 keV, = or > 230 keV and = or > 1.6 MeV) at the magnetic equator in the outer radiation zone.
