| Abstract: | During the first Chinese national antarctic research expedition, there is a high whistler activity at Great Wall Station on Jan. 20, 1985 and valuable whistler direction finding data are obtained by using our GM type VLF broadband receiver.The continuous observation from 17h20m to 18h50m shows that the exit points of whistler are situated in a strip of about 80 km wide in longitudes with an azimuthal direction 20°-40° E of N between 47.6° and 52.0° geomagnetic latitude. The ducts are all in the same strip region and there are no strong across L or longitudinal drifts. Therefore it is concluded that it is a process of the duct formation, growth, evalution into cluster and decay instead of the drifting of ducts into the "viewing window" of the station. |
