Sokolov report on behalf of larger collaboration:\n\nThe field of GRB 111029A (Troja et al., GCN#12498) was observed\nwith the Zeiss-1000 telescope of SAO RAS (Russia) on October 29/30 night.\n12 x 300 sec. in Rc and 12 x 300 sec. in Ic images were obtained\nunder the good conditions and the seeing 2\" (FWHM of stellar-like objects\nat the co-added images). The observation started at 21:31:21 October 29\n(since 11.8 hours after the trigger), finished at 00:33:51 October, 30 UT.\n\nNo optical counterpart was detected within the XRT 1\".9 error circle\n(according to http://www.swift.ac.uk/xrt_positions/ ) up to the 3 sigma\nlimiting magnitudes R_lim = 24.6 and I_lim = 23.3. The calibration was done\nagainst R2 and I magnitudes of nearby USNO B-1.0 stars. The Rc and Ic images\ncan be found at ftp://ftp.sao.ru/pub/grb/GRB111029A/GRB111029A.jpg\n\nThe closest object is located 4\".65 South-West from the center of XRT\nerror circle. The brightness of this object is R = 22.99 +/- 0.32,\nI = 21.79 +/- 0.28 (the high error is due to calibration) and the\ncoordinates are R.A.(J2000) = 02:59:07.71, Dec.(J2000) = +57:06:35.5,\nwith the uncertainty 0\".21. Due to cosmological nature of GRBs\nthis object probably can not be related to the GRB 111029A.",
