We present a map of the cosmic far-ultraviolet (FUV; 1360-1710A) continuum background over the most of the sky. The map was obtained with the “Spectroscopy of Plasma Evolution from Astrophysical Radiation” instrument (SPEAR/FIMS), flown aboard the STSAT-1 satellite mission. The cosmic FUV flux distribution is consistent with what is generally believed to be its dominant component, light from early-type stars scattered by interstellar dust. We are developing a dust-scattering radiative transfer model to fit the FUV continuum data. The coverage and quality of our data should allow us to place simultaneous constraints on the dust properties and illumination parameters. We investigate the total FUV interstellar radiation field and comparisons of the diffuse FUV continuum map with maps of reddening, N(HI), and Hα. The SPEAR (FIMS) is supported by NASA grant NAG5-5355 and flies on the STSAT-1 Mission, supported of the Korea Ministry of Science and Technology.
