Saxton et al. (ATel #11182) reported the discovery of a bright X-ray transient toward the Large Magellanic Cloud. The object is located in the field regularly monitored by the OGLE-IV Survey. The reported coordinates are consistent with those of a bright (I = 15.04 mag), red (V-I = 3.07 mag) star OGLE-LMC173.6.14223 (R.A. = 05:36:30.20, Decl. = -67:59:37.0, J2000.0). It has a relatively high proper motion (mu_RA = 10.07 +/- 0.14 mas/yr, mu_Decl = 45.49 +/- 0.14 mas/yr) according to the catalog of Poleski et al. (2012). The object is likely a foreground (Galactic) dwarf star.
