Abstract
Five sounding rockets were launched from Syowa Station in Antarctica; three in 1984 and two in 1985 by the 25th and 26th wintering parties of Japanese Antarctic Research Expedition. The purpose of the former three was to investigate the causality between auroral particle energy spectra and the auroral light emissions at various stages of polar substorm activities. The latter two aimed at the study of the wave-particle interaction processes on auroral field lines. Scientific objectives and related instrumentations are briefly described. Geomagnetic conditions at the rocket launchings and the flight performances together with outlines of scientific results compared with ground-based observations are presented.
