AB: We have examined Michelson Interferometer OH airglow temperature data to investigate solar cycle and long-term variations of mesospheric temperatures at the South Pole Station, Antarctica (90o S). The aforementioned MI has been making observations of temperature and airglow emissions since 1992 during austral winter night. These continuous measurements during the six months of each polar winter allow us to investigate the effects natural variability of Solar flux on the Antarctic mesospheric thermodynamics. In this paper we present our results to elucidate solar cycle and trend terms in the MI temperature time series data. In addition, superposed epoch studies have been carried out in order to determine the mesospheric seasonal variation at South Pole. Comparisons with other Antarctic mesospheric temperature measurements [Hernandez, 2003; and French et al, 2005] will be presented to highlight similarities and disagreements among these studies and in particular 2002 mesospheric temperature will be discussed.
