Scientific paper

The autors use spatial and spectroscopic information from IUE spectra in the range 1,150 - 1,950 Å to demonstrate that Sk -69°202, the star coinciding positionally with the LMC supernova has disappeared from sight. Two weaker sources, named star 2 and star 3 in the astrometric analysis of the image of Sk -69°202 before the supernova outburst, are still present in the ultraviolet spectra. The authors isolate their spectra and give a spectral classification. They conclude that Sk -69°202 is the progenitor of the LMC supernova.
