Analyses of geomagnetic pulsations in Antarctic region during magnetic storm on March 24, 1991

Geomagnetic pulsations at Great Wall Station and Zhongshan Station of Antar ctica during magnetic storm on March 24, 1991 are analysed. In this paper t he beginning time and characteristics of various pulsations are given and c omparison analysis are made for two stations. All of them are helpful for u nderstanding different behaviour of various pulsations at dayside and night side or at high-latitude and mid-latitude and for realizing the relationshi p between pulsation morphology and storm process during a magnetic storm in Antarctica.
