Recent observations (Matsumoto et al., 1988) indicate that at submillimeter wavelengths the spectrum of the cosmic background radiation (CBR) deviates from that of Planckian blackbody with a temperature T0R = 2.76 K. The relative excess of the flux ζ(v) = [F(v) – F0(v)] / F0(v) (where F(v) and F0(v) are the registered flux and the flux of the blackbody radiation at the frequency of the observations) are 0.6 at a frequency v1 = 380 GHz (λ = 709 μm) and 3.4 at a frequency v2 = 624 GHz (λ = 481 μm).
