Precipitating Electrons Observed on Board the Japanese Antarctic Sounding Rockets S-310JA-1 and S-310JA-2
Cylindrical electrostatic analyzers on board the Japanese Antarctic sounding rockets S-310JA-1 and S-310JA-2 launched on February 13,1976 and on February 10,1977,respectively, at Syowa Station, obtained the energy spectra of energetic electrons in the Antarctic polar ionosphere.
