New results from reduction of data from the space experiment Relikt-1 (investigation of the anisotropy of the cosmic microwave background at 37 GHz) are presented. With 99 percent confidence, an anomalous signal is detected in a region of area of about 1 sr, centered at RA = 1 hr 30 m, Dec. = -10 deg (l = 150 deg, b = -70 deg). The brightness temperature of the signal is -71 +/- 43 micro-K with 90 percent confidence, including systematic errors. The nature of the signal cannot be explained by effects of the apparatus or by radio emission of known sources; there are reasons to believe that the signal has a cosmological origin. For a model of cosmological signal with scale-invariant spectrum, i.e., in terms of a power-law spectrum with n = 1, an estimate is presented, for the rms, of a quadrupole component of 6 x 10 exp -6 to 3.3 x 10 exp -5 with 90 percent confidence, including systematic errors.
