For studies of diffuse gases in the temperature range 105 – 106K, observations of O VI absorption in the spectra of background stars provide an important supplement to information from surveys of soft x-ray emission. We report here the first observations of O VI absorption recorded at a resolution of 3 km s−1 for the stars 15 Mon and HD 64760. Both stars are behind regions that are suspected to be old supernova remnants. The observations were made with the Interstellar Medium Absorption Profile Spectrograph (IMAPS) during its flight on the ORFEUS-SPAS II mission in late 1996.
