We report here the significant occurrence of pulsating aurorae in the high latitude post-noon auroral oval. Observations of aurorae at Davis, Antarctica (Inv. 74.5¿S, Geog. 78.0¿E, 68.6¿S) during the 1988 Austral winter indicate pulsating auroal activity peaks at around 14.5% in the period 1330--1400 magnetic local time (MLT). Post-noon high latitude pulsating aurora is typically a less than 250 R enhancement on a 1 kR background in the OI emission at 558 nm. Pulsation periods tend to be longer at 20--30 s compared to average auroral zone fluctuations of around 2--10 s. Similar to auroral zone stations, the optical fluctuations are always accompanied by Pi(c) magnetic pulsations. Weak Kp and IMF trends are present in the data. ¿ American Geophysical Union 1990
