From a comparison between ground aurora and DMSP particle data, energetic electrons higher than 1 keV are responsible for the postnoon band aurora. It is remarkable that the postnoon band aurora shows a periodic latitudinal movement with its period about 125s to 160s. It is also noted that a bright region moves from the west to the east along the longitudinal direction within the band aurora. These charactreristics are partly similar to auroral behavior obtained in our previous observations at Ny-Alesund in Spitzbergen.}, pages = {19--27}, title = {Postnoon aurora observed at Zhongshan Station, Antarctica - A case study -}, volume = {11}, year = {1998} }
