Abstract

We have analyzed 7 years of OGLE-III photometry for the SMC X- ray pulsar XTE J0053-724 (SXP46.6). The optical counterpart is star 30 of field SMC108.8 in the OGLE-III database. It corresponds to the Be star marked as Star B on the finding chart of Buckley et al. (2001, MNRAS, 320, 281). M. Coe has pointed out on his web site (www.astro.soton.ac.uk/~mjc/smc/ Finders/sxp46.6.jpg) that this star is most consistent with the Chandra X-ray position (00:53:53.8; -72:26:35).
