Holland et al, GCN12472)\nwith the optical three color (g, Rc, and Ic) CCD camera attached\nto the MITSuME 50 cm telescope of Akeno Observatory, Yamanashi, Japan.\nThe follow-up observation was started at 18:09:58, ~ 57 min after the\nBAT trigger because of bad weather.\n\nWe did not find any new point source within the enhanced XRT error\ncircle (A.P. Beardmore et al, GCN12478) in three bands.\n\n\nPhotometric results and are listed below. We used GSC2.3 catalog for\nflux calibration.\n\nT0+[s]      MID-UT     T-EXP[sec]      g'             Rc           Ic\n---------------------------------------------------------------------------------\n  +7317      19:54:13        540           >17.8       >17.7       ---\n  +10426    20:12:52        360            ---             ---        >16.5\n---------------------------------------------------------------------------------\nT0+ : Elapsed time after the burst [sec]\nT-EXP: Total Exposure time [sec]",
