M. ; Wilkinson, D. T. Abstract The authors have searched for small-scale anisotropy in the cosmic microwave background using the maser receiver and 140 foot telescope of the NRAO, operating at a frequency of 19.5 GHz. The half-power beamwidth was 1arcmin.5. Beam switching by 4arcmin.5 was used in order to minimize variable contributions from ground and atmospheric emission and from the instrument. The data set an upper limit of (ΔT/T)rms < 4.5×10-5 at the 95% confidence level on fluctuations at the 4arcmin.5 scale.
