Unmanned observatory for auroral physics study on the Antarctic Continent-Multipoint ground-based observations during the IMS period (1976-1978)-

Abstract

The International Magnetospheric Study (IMS) was carried out for three years from 1976. The Japanese Antarctic Research Expedition (JARE) participated in this IMS project. The main purpose of the IMS project in JARE was the synthetic observation of polar magnetic substorms. In order to study polar magnetic substorms, a multipoint ground observation network was planned around Syowa, including unmanned stations. In the construction of an unmanned observatory system in Antarctica, there have been difficulties, such as insuffcient information about enviromental conditions, the construction support capability, power supply and others. During the IMS period, the U. S. A., former Soviet Union, Australia and the United Kingdom also started to develop unmanned observation systems. In this report, we describe the development of a JARE unmanned observatory for upper atmosphere physics and also the scientific results.
