Scientific paper

The paper presents IUE and optical observations of Nova LMC 1990 Number 2, the first recurrent nova to be observed outside the Galaxy. The ultraviolet observations reported here caught the nova at UV maximum; no P Cygni profiles developed on the resonance lines, suggesting that very little mass was ejected and the outburst was not spherical. The integrated UV luminosity at UV maximum was 2.9 x 10 to the 38th ergs/s. Thus the luminosity exceeded the Eddington limit for a 1-solar-mass white dwarf.
