TITLE: GCN CIRCULAR NUMBER: 7062 SUBJECT: GRB 071112C: Optical and NIR afterglows observed with KANATA DATE: 07/11/12 20:07:47 GMT FROM: Makoto Uemura at Hiroshima U M. Uemura, M. Sasada, A. Arai, and T. Uehara (Hiroshima Univ.), report on behalf of the KANATA GRB team: We performed optical-NIR observations of the field of GRB 071112C (GCN Circ. 7059) with TRISPEC attached to the "KANATA" 1.5-m telescope. We found a fading object at the position of the optical afterglow detected with UVOT. Our preliminary results are below: time(UT) mag. exposure_time Nov. 2007 (sec) 12.77880 17.76 +/- 0.14 V 30sec * 10 12.77911 16.39 +/- 0.22 J 25sec * 9 12.78674 18.66 +/- 0.20 V 123sec * 5 12.78672 17.16 +/- 0.17 J 120sec * 5 Comparison star: V-band: GSC2.3 02:36:55.72 +28:21:03.7 V=14.15 J-band: 2MASS 02:36:55.72 +28:21:03.7 J=12.674 The large errors of magnitudes are due to the rapidly fading trend of the afterglow. Further observation and analysis are ongoing.
