Low resolution, time-resolved ultraviolet spectra were obtained with the Hubble Space Telescope for the post--nova GQ Muscae on September 2, 1994. We obtained satisfactory data during 3 HST orbits which together cover about 90% of the GQ Mus 85.5 min binary orbital period. The mean spectrum shows a strong, blue continuum which is only slightly flatter than a Rayleigh-Jeans spectra energy distribution. The UV luminosity is LUV ~10(35) erg s(-1) . Moderately strong emission lines from He II, C IV and possibly other high ionization species are present. No significant variability is found as a function of orbital phase and the random variability is <= 10 % throughout the 1300--2100 Angstroms spectral region. The results from these observations are discussed in terms of a cooling white dwarf model for this post--nova.
