[118.01D] Cosmic Microwave Background Anisotropy Measurements from the South Pole: UCSB's 1994 Results

The UCSB Experimental Cosmology Group has made three deep observations of the CMB anisotropy on degree angular scales. The data were taken between January 1, 1994 and January 22, 1994 and used the Advanced Cosmic Microwave Explorer (ACME) telescope with two different receivers operating at seven frequencies between 26 and 45 GHz. Significant correlated structure is observed in the first observation as well as in the second and third overlapping observations. The amplitude and spectrum of the observed structure has been characterized and will be discussed in relation to favored models of structure formation and other anisotropy measurements.
