A review of the historical development of our knowledge of the geographical distribution of aurora in the Antarctic. Published results for the IGY and later years are summarized; data on azimuth of auroral arcs at various hours of the day are given; and the equatorward expansion and broadening of the auroral belt with worldwide features of magnetic storms are noted. Specific instances of auroral belt positions during very great and very weak magnetic disturbances are discussed. This belt appears to be linked with the corresponding belt in the Arctic. Spatial relationships to geomagnetic and other geophysical phenomena are also summarized. 21 pp.
