Fox (PSU) report:\n\nWe imaged the location of the short GRB 111020A (GCN 12460) with GMOS on the\nGemini-South 8-m telescope on 2011 October 21.01 UT (mid-time of 17.7 hours\npost-burst).  We obtained 9x180s exposures in i-band with 0.8\" seeing.\n\nWe find no sources within the enhanced XRT error circle (GCN 12463) to a\n3-sigma limiting magnitude of i~25 mag.\n\nHowever, we find two faint objects just outside of the XRT error circle with\ncoordinates (J2000):\n\nS1:\nRA = 19:08:12.501\nDec = -38:00:41.80\n\nS2:\nRA = 19:08:12.698\nDec = -38:00:44.46\n\nS1 has a brightness of i~23.7 mag and appears to be point-like. S2 is\nfainter, at the threshold of detectability with a brightness of i~25 mag.\n\nThe nearest galaxy is located at:\n\nG1:\nRA = 19:08:12.231\nDec = -38:00:48.80\n\nwith a magnitude of i~23.3 mag, and 6.2\" from the center of the XRT error\ncircle.",
