We have used the imaging instrumentation on the Dynamics Explorer 1 (DE) satellite to measure the intensity of the diffuse ultraviolet (UV) radiation on two great circles about the sky. We find that the isotropic component of the diffuse UV radiation (possibly of extragalactic origin) has an intensity of 530 ±80 units (a unit is one photon cm−2 s−1 sr−1 A−1) at a wavelength of 150 nm. The galactic component of the diffuse UV radiation has a dependence on galactic latitude, which requires strongly forward-scattering particles if it is produced by dust above the galactic plane.
