Pioneer 10 Observations of the Solar Wind and Its Interaction with Jupiter: Plasma Electron Results

Abstract

Previously we reported (Wolfe et al., 1974a) that during the inbound portion of the Jovian flyby (see Hall, 1974 for a description of the Pioneer 10 flyby geometry) the Jovian magnetosheath was encountered for two extended time intervals: from 2031 UT (Ground Received Time) on November 26, 1973 to 2038 UT on November 27, 1973, corresponding in radial distance from Jupiter of 109 R _J and 96 R _J, respectively; and then from 0318 UT on December 1, 1973 to 1415 UT on December 1, 1973, corresponding in radial distance from Jupiter of 54 R _J and 46.5 R _J. In Wolfe et al. (1974b) we summarize the general features of the solar wind interaction with Jupiter. In Intriligator (1975) we summarize the plasma electron observations obtained in the Jovian magnetosphere. In this paper we summarize the plasma electron data obtained in the Jovian magnetosheath.
