The observation started at 01:59:08 UT on\nOctober 17, 2011, approx.  5.5 hours after the Swift trigger.\nWe report no detection of the optical counterpart on the\nunfiltered images within the error circle given by SWIFT-XRT\n(Evans et al., GCN 12441). The upper limit of 19.5 mag in\nR-band was estimated using nearby sources from GSC2.2\ncatalogue.\"",
