On the assumption that the ionization of the intercloud gas in the vicinity of the sun is indeed due to direct photoionization, a self-consistent model is derived from the observations of the Copernicus satellite for unreddened stars which allows one to infer directly the interstellar photon flux in the range from 1750 A to 504 A. At the long-wavelength end, this flux is consistent with that derived by Witt and Johnson (1973) in the range 4250 A to 1250 A. The results suggest that, in the immediate vicinity of the sun, interstellar hydrogen that is not lumped up in concentrations will be roughly 95% ionized. The spectral distribution of the flux indicates that it originates from early-type B stars.
