The intensity ratio I (557.7 nm) / I (427.8 nm) at Zhongshan Station in Antarctica
Auroral intensity ratios at Zhongshan Station in Antarctica on 8 April 1999 are studied, along with variations in penetrated electron energy. Ratios of I (557.7 nm)/ I (427.8 nm) during the quiet period were from 5 to 22, and I (630.0 nm) / I (427.8 nm) ranged from 1 to 2.76. These variations were n...
