Abstract

The spectrum of the night sky has been measured in the frequency range from 3 to 40

{cm}^{- 1}

using a fully calibrated liquid-helium-cooled balloon-borne spectrophotometer at an elevation of 39 km. A model based on the known molecular parameters was used to subtract the atmospheric emission. In the frequency range from 4 to 17

{cm}^{- 1}

, the spectrum of the background radiation is that of a blackbody with a temperature of

{2.99}_{- 0.14}^{+ 0.07}
