AFOS (Antarctic Fibre Optic Spectrometer) is a 30cm Newtonian telescope which injects light through six 30m long optical fibres onto a 240-800nm spectrograph and 1024x256 pixel CCD camera. First deployed to Admundsen-Scott base in the summer of 1998 the telescope is mounted on a dual-telescope alt-az mount and has been designed to probe the suitability of the atmosphere above South Pole for astronomy in the UV and Visible wavelength regions. Improved and refitted in 2000/2001 AFOS has successfully collected data from the 2000 lunar eclipse above the South Pole and this data is presented here. A season of data observing a number of bright standard A and O-type stars was collected during the winter of 2002 and continues during the winter months of 2003. These observations have been designed to probe the UV-cutoff wavelength atmospheric absorption due to oxygen and water and the effect of auroral emissions on observations. The initial results of these obervations are also presented.
