Scientific paper

This paper reports the significant occurrence of pulsating auroras in the high-latitude post-noon auroral oval. Observations of auroras at Davis, Antarctica during the 1988 austral winter indicate pulsating auroral activity peaks at around 14.5 percent in the period 1330-1400 MLT. Postnoon high latitude pulsating aurora is typically a less than 250 R enhancement on a 1 kR background in the O I 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.
