A CINEMATOGRAPHIC DISPLAY OF OBSERVATIONS OF LOW-ENERGY PROTON AND ELECTRON SPECTRA IN THE TERRESTRIAL MAGNETOSPHERE,

Abstract

A massive series of observations of the differential energy spectra of proton and electron intensities over the energy range of approximately 300 eV to 50 keV within the earth's magnetosphere and its environs has been obtained with an array of electrostatic analyzers borne on the earth-satellite OGO 3. In order to supplement the presently existing publications derived from these observations and to provide further insight into the distributions of low-energy charged particles within the earth's radiation zones over geocentric radial distances of approximately 2 to 20 RE (RE, earth radii) we have utilized a SC 4020 microfilm plotter to construct a cinematographic display of the differential energy spectra of proton and electron intensities which spans a complete circuit of the spacecraft around the earth, or about 50 hours of substantially continuous observations beginning at 1330 U.T. on July 14, 1966. This cinematographic display comprises approximately 18,000 individual frames and summarizes some 550,000 intensity measurements. A description of the methods and graphic results is furnished as an aid in interpretation of this visual presentation of the observations. (Author)
