摘要：

Results of a search for small-scale anisotropy in the cosmic microwave background (CMB) are presented. Observations were made at the South Pole using the Viper telescope, with a 0 degrees.26 (FWHM) beam and a passband centered at 40 GHz. Anisotropy band-power measurements in bands spanning the range of l in which the first acoustic peak is expected (bands centered at l = 108, 173, 237, 263, 422, and 589) are reported. Statistically significant CMB anisotropy is detected in all bands.
