Abstract: We present a survey of O VI λ1032 emission in the Milky Way using data from the Far Ultraviolet Spectroscopic Explorer ( FUSE ) satellite. The observations span the period from launch in 1999 to 2003 July. Our survey contains 112 sight lines, 23 of which show measurable O VI λ1032 emission. The O VI λ1032 emission feature was detected at all latitudes and exhibits intensities of 1900-8600 photons s -1 cm -2 sr -1 . Combined with values from the literature, these emission measurements are consistent with the picture derived from recent O VI absorption surveys: high-latitude sight lines probe O VI-emitting gas in a clumpy, thick disk or halo, while low-latitude sight lines sample mixing layers and interfaces in the thin disk of the Galaxy.
