The UC Santa Barbara CMB anisotropy group has made three excursions to the South Pole to obtain data on degree scale anisotropies. The most recent trip occurred from November, 1993 to January, 1994. Data were taken with the UCSB Advanced Cosmic Microwave Explorer (ACME), using two different receivers, operating from 26-36 GHz and from 38- 45 GHz. The receivers incorporate High Electron Mobility Transistor (HEMT) amplifiers operated at liquid Helium temperatures, and acheived noise temperatures of 15 K. Status of the systems and sample data will be presented.
