Uehara (Hiroshima Univ.), \nreport on behalf of the KANATA GRB team:\n\n  We performed optical-NIR observations of the field of \nGRB 071112C (GCN Circ. 7059) with TRISPEC attached to \nthe \"KANATA\" 1.5-m telescope.  \n\n  We found a fading object at the position of the optical \nafterglow detected with UVOT.  \nOur preliminary results are below:\n\ntime(UT)       mag.              exposure_time\nNov. 2007                        (sec)\n12.77880       17.76 +/- 0.14 V  30sec * 10\n12.77911       16.39 +/- 0.22 J  25sec * 9\n12.78674       18.66 +/- 0.20 V  123sec * 5\n12.78672       17.16 +/- 0.17 J  120sec * 5\n\nComparison star: \nV-band: GSC2.3 02:36:55.72 +28:21:03.7 V=14.15\nJ-band: 2MASS  02:36:55.72 +28:21:03.7 J=12.674\n \nThe large errors of magnitudes are due to the rapidly \nfading trend of the afterglow. \nFurther observation and analysis are ongoing.",
