The advantage of carrying out such observations from the South Pole is that the high atmospheric transmission and stability allows us to apply the polarimetry techniques to regions of low column density that cannot be studied at other sites. Magnetic fields are believed to play important roles in infall processes such as the one that is occurring in the Milky Way's nucleus, where a black hole of several million solar masses is believed to have formed. Successful tests on the Viper telescope January 20-26, 1999. Software testing and source selection during February - August 1999. The primary science goal for austral Winter 2000 will be to map the magnetic field in the central few hundred parsecs of the Galaxy.
