Abstract:

The data of various geomagnetic pulsations observed at Zhongshan Station from Feb.9,1992 to Feb.9,1993 are analysed in this paper and the excitation mechanisms of pulsations at Antarctic polar cusp are discussed primarily. By the observation and analyses of geomagnetic pulsations at Zhongshan Station, the phenomena of upper atmospheric electromagnetic environment, interaction between solar wind and the magnetosphere etc. at Antarctic polar cusp can be further realized.
