Abstract (from CDS):

We report the identification of the optical counter-part of the SMC super-soft X-ray source 1E0035.4-7230 with a variable star of magnitude B=19.9-20.2 within the 40" Einstein error box. The star shows strong UV excess, a hot, blue continuum and weak lines of high ionization. The lines are redshifted by 3-4A, indicating SMC membership. This object appears similar to CAL 83 and CAL 87 and is probably a binary system hosting an accreting, hydrogen burning white dwarf.
