Palazzi (INAF-IASFBo) on behalf of a larger\ncollaboration report:\n\nWe observed the field of GRB 111123A (Stamatikos et al. GCN 12587) with\nthe 3.6m TNG equipped with the NICS near-infrared camera. A sequence of\nJHK band images were acquired starting on Nov 24.238 UT (i.e. ~11.5 hours\nafter the burst event).\n\nAn object is detected in a stacked 20 min exposure image inside the\nenhaced XRT error circle (Goad et al. GCN 12590) at the following\ncoordinates (J2000):\n\nR.A. = 10:19:23.14\nDec. = -20:38:41.0\n\nwith an uncertainty of ~ 0.3\", consistent with the position of the object\nreported by Xu et al. (GCN 12589). The source has a magnitude K=19.4 +/-\n0.3 (calibrated against the 2MASS catalogue). The source is not detected\nin the shorter exposures (10 min) J and H-band images down to the\nfollowing 3sigma upper limits: J>19.7, H>20.5. At the present stage, it is\nnot possible to say anything about source variability.\n\nWe thank the TNG staff for their support, in particular Luca Di Fabrizio.",
