Skvarc on behalf of PIKA\nobserving program at Crni Vrh Observatory:\n\nWe observed the afterglow of GRB 071112C (Perri et al., GCN 7059) with 60-cm\nCichocki robotic telescope at Crni Vrh Observatory, Slovenia in rather poor\nseeing conditions. The series of nineteen 90 second connsecutive exposures\nwith Rc filter started at 18:35:51UT, 118 seconds after the GCN notice time.\nWe confirm optical afterglow found by UVOT. The object measured coordinates\nare RA=02:36:50.95, DEC=+28:22:16.8 (J2000). The object was clearly detected\non first nine frames after which it dropped below the detection limit.\n\nPhotometry results are given in table below. The magnitudes are derived\nusing comparison stars from the USNO-B1 catalogue. The 3-sigma limiting\nmagnitude in R filter is around magnitude 18.2.\n\nTime refers to exposure start.\n\nTime (UT)           Exposure(s) Mag.    Err.
