Description
We report on a Chandra observation of the transient low-mass X-ray binary and type-I X-ray burst source 2S 1711-339 (Carpenter et al. 1977,MNRAS,179,270; Wilson et al. 2003,ApJ,596,1220). The 2S 1711-339 region was observed with the Chandra ACIS-S3 CCD array for 25 ks on 2003 February 07. A total of 64 counts were detected from a source at R.A. = 17h:14m:19s.73, decl. = - -34:02:46.9 (J2000), a position consistent with the precise position of 2S 1711-339 obtained earlier during outburst.
