The acquisition and transfer system of observational data of Syowa Station using INMARSAT link have been developed. Using this system, near-realtime data of Antarctica become available in Japan. To apply these data to the space weather forecast, J-index is introduced for a realtime evaluation of geomagnetic activities, which showed a good correlation with the K-indices.
