New measurements of the emission spectrum of the night sky have been made in the frequency range from 1.7 to 40 cm/sup -1/ using a fully calibrated, liquid-helium--cooled, balloon-borne spectrophotometer. The results show that the spectrum of the cosmic background radiation peaks at 6 cm/sup -1/ and is approximately that of a 3-K blackbody out to several times that frequency. However, the data show deviations from a simple blackbody curve.
