Duval \n(Stockholm), report on behalf of a larger collaboration:\n\nWe observed the afterglow candidate of GRB 131231A (Sonbas et al., GCN \n15640; Xu et al., GCN 15641) using the 2.56m Nordic Optical Telescope \n(NOT) equipped with MOSCA. Observations started at 22:05:40 UT on 2013 \nDec 31 (i.e., 17.3 hr after the Fermi trigger).\n\nThe afterglow candidate noted by Xu et al. (GCN 15641) has decayed to \nR=18.6, using the same calibration. We thus suggest that this source is \nvery likely the afterglow of GRB 131231A. The coordinates of the \nafterglow can be refined to\n\nR.A. = 00:42:21.665\nDec. = -01:39:10.61\n\nwith an error of 0.3\".\n\nWe also wish a happy new year to everyone.",
