Abstract:

The passage outlined of the dispersion law over time of the frequency that three different aurora(strong,middle,weak) had occurred during the night(GUT 11:00-24:00) in Antarctic Zhongshan Station has relationship with geomagnetic field disturbance by analysizing the observed aurora and disturbance. The weak aurora appeared at 10:00 o'clock and its frequency of occurrence reached the peak at 15:00;The middle appeared at 11:00,reached the peak during 21:00-22:00, and especially its frequency is stable at 19:00; the strong ones occurred at 16:00 and reached the peak during 20:00-21:00. The dispersion over time of frequency that all kinds of aurora occurred is approximately compliant with the disturance of geomagnetic field. The weak aurora accompanies disturbance of small amplitude. The strong aurora correspond with large amplitude. The time of aurora occurrence is partially the same as that of disturbance.This partially correspondence relates to the various status of aurora. Furthermore,this various aurora status is affected by space environment.
