Summary:In conjunction with the scientific program of the International Magnetospheric Study (IMS), an unmanned ground-based observatory was constructed in the inland of the Antarctic Continent about 150km south east of Syowa Station. Electric power source was supplied from batteries charged with a wind generator and it was maintained satisfactorily for more than 4 years during the period from 1977 to 1980. Several kind of instrumentations, fluxgate, induction magnetometer and riometer, were installed for the study of polar region phenomena. On the basis of aurora and geomagnetic variations observed at Syowa, Mizuho and unmanned station (A1), it is found that small scale auroral electrojet currents really corresponded to auroral luminous regions and were able to be assumed as line currents.
