Scientific paper

The results of seventeen years of Voyager observation of diffuse ultraviolet background radiation have been reported by Murthy et al. (1999, ApJ, 522, 904). The most important result is that there are discovered to be large numbers of locations on the sky, at all galactic latitudes, where the diffuse background is not detected at all, with an upper limit, in the best cases, of 30 photons cm-2 s-1 sr-1 ÅBut, there are also many locations, and again at all galactic latitudes, where a considerable flux of ultraviolet light is seen. We present a map showing the locations and brightnesses of these positive detections, and we exhibit typical spectra. At the moment, the nature of the emitting diffuse objects is not understood, except that, since these objects are observed to occur at low galactic latitudes (as well as at high galactic latitudes), they can hardly be extragalactic in nature. The Voyager ultraviolet spectrometers have a field of view that is 0.1^circ × 0.87^circ. Murthy et al. used Voyager spacecraft jitter as a means of excluding observations that could be attributed to a point source in the field of view. The spectral range of the observations is from well below the interstellar gas photoionization edge at 912 Å (which is detected), through Lyman alpha at 1216 Åand continuing (but with much lower sensitivity) to 1700 Å
