  We report on initial progress in a program of optical identification of
supersoft X-ray sources in M31, pursued mainly with the WIYN telescope. We
propose the identification of one supersoft X-ray source with a variable star,
which we believe to have been a classical or recurrent nova in outburst in
September 1990. The nova remnant must have been still a supersoft X-ray sources
5 years after this observation, when it was observed with ROSAT.
