Immler et al, GCN12471)\nwith the optical three color (g, Rc, and Ic) CCD camera attached\nto the MITSuME 50 cm telescope of Akeno Observatory, Yamanashi, Japan.\n\nThe observation started on 2011-10-23 9:16:56 UT (~16.8 h after the burst).\nWe did not find any new point source within the Swift XRT error\ncircle (G. Stratta et al, GCN12482) in three bands.\n\nPhotometric results and are listed below. We used GSC2.3 catalog for\nflux calibration.\n\nT0+[day]      MID-UT     T-EXP[sec]      g'             Rc           Ic\n---------------------------------------------------------------------------------\n 0.71519     9:47:22        3060         >18.4       >16.5       >16.5\n---------------------------------------------------------------------------------\nT0+ : Elapsed time after the burst [day]\nT-EXP: Total Exposure time [sec]",
