Abstract:	A survey of diffuse interstellar sight lines observed with the Far Ultraviolet Spectroscopic Explorer has led to the serendipitous discovery of a high–ionization nebula around the hot white dwarf KPD 0005+5106. The nebula has an O VI λ1032 surface brightness of up to 25,000 photons s−1 cm sr−1, making it the brightest region of extended O VI emission in our survey. Photoionization models using the incident white dwarf continuum successfully reproduce the observed O VI intensity. The O VI emission arises in the highly ionized inner region of a planetary nebula around KPD 0005+5106. This newly discovered nebula may be one member of a class of high-ionization planetary nebulae that are difficult to detect in the optical, but which can be easily identified in the ultraviolet.
