Uklein,\nreport on behalf of the SAO RAS GRB follow-up team:\n\nWe observed the field of GRB 110807A (D'Elia et al, GCN 12253)\nwith the 6-meter BTA + Scorpio on August 7.843 -- 7.857 UT\n(observations were started since 16 minutes after the BAT trigger).\n\nWe obtained 21 x 30 sec. exposures in Rc band. At our stacked image\n(seeing = 1\".9), inside the XRT error circle we clearly detected\nonly one object with the following coordinates:\nR. A. = 18:34:52.42\nDec. = -08:45:57.08,\nwith approximately error 1\" (all coordinates for Epoch = 2000).\n\nThe brightness of the object were measured as R = 23.44 +/- 0.34\n(no extinction correction were made). Calibration were done against\nthe magnitude R2 = 17.85 of the USNO-B.1 star 0812-0420010\n(R.A. = 18:34:51.24, Dec. = -08:45:40.1).\n\nWe also noted presence of the other object just outside from the XRT\nerror circle to the North-West which is marked as USNO-B.1 star\n0812-0420027 (R.A. = 18:34:51.86, Dec. = -08:45:52.3).\nAt our image this object is extended along the South-East direction\nand probably may be two or more objects.\n\nZoomed image from BTA can be found at\nftp://ftp.sao.ru/pub/grb/GRB110807A/GRB110807A_BTA.jpeg\n\nThe message may be cited.",
