Observations of Auroral-Zone Precipitating Electrons by the Antarctic Rockets (a. Precipitating Particles and Auroras) (Proceedings of the First Symposium on Coordinated Observations of the Ionosphere and the Magnetosphere in the Polar Regions (Part I))

Abstract

During one year from January 1976, five sounding rockets carrying the electron detector were launched from Syowa Station, Antarctica. One of them was made on a geomagnetically quiet time, while the others all encountered a certain degree of auroral disturbance. The rocket-borne detector consists of both proportional and plastic scintillation counters and can measure high energy electrons greater than 40 keV. Preliminary results thereby obtained are presented, giving an account of characteristics of vertical profile and pitch angle distribution of energetic electrons during auroral disturbances, compared with those for the quiet time.
