Scientific paper

Observations of Nova Mus 1983 obtained since its discovery in January 1983 are summarized, with an emphasis on visual and IR photometry and spectroscopy performed at ESO. The data are presented graphically and characterized in detail. Nova Mus 1983 is classified as a fast nova with t3 = 40 d, Vmax = 7.0 mag, M(V) = -7.75, and distance 4.8 kpc. By 1984 the spectrum was dominated by strong nebular emission lines, including the forbidden coronal lines of Fe X at 607.4 nm and Fe XIV at 530.3 nm. The possible mechanisms responsible for the soft X-ray emission detected (at approximately constant count rates) by Exosat in April, July, and December 1984 are discussed.
