Abstract:

In this paper a comparison of geomagnetic micropulsation observed in Antarctica and Beijing during the first Chinese exploration in Antarctica has been done. From the analysis it is concluded that during geomagnetic quiet days the quiet pulsation activity is dominated in both areas, and Pc1/Pc4-5 pulsations occur sometimes in Antarctica and Pc3 pulsations in Beijing, and that Pi pulsations hardly occur. There is no corresponding pulsation in both areas in universal time. However, during geomagnetically disturbed days the occurence of Pi pulsations in both areas increases and they have a good corresponding relation, but those in Antarctica are stronger than that in Beijing.
