QUaD is a 31 pixel array of polarization sensitive bolometer pairs coupled to a 2.6 m Cassegrain radio telescope. The telescope is attached to the mount originally built for the DASI experiment and located at the South Pole. The telescope system is described along with details of instrumental characterization studies which we have performed. A first season of CMB observations is complete and the second season underway. Details of the current status of these observations and their analysis are presented.
