Description:
A far-ultraviolet spectrometer and several far-ultraviolet photometers have been carried to an altitude of 347 km to measure the spectrum of three regions at high galactic latitudes. After correction for O I airglow and for stars in the field of view, a nearly uniform residual intensity of 285 plus or minus 32 photons per (sq cm s sr A) is found over the spectral range 1230-1680 A, along with some evidence for a sharp rise in intensity longward of 1680 A. It is argued that the signal is not likely to be due to light scattering from interstellar dust. The flat spectrum could represent the integrated light of distance galaxies. The sharp rise must be due to some other phenomenon.
