Kawai(Tokyo Tech)\nreport on behalf of the MITSuME and OISTER collaboration:\n\nWe observed the field of GRB 150910A (Pagani et al., GCNC 18264)\nwith the optical three color (g', Rc and Ic) CCD camera attached\nto the Murikabushi 1m telescope of Ishigakijima Astronomical\nObservatory.\n\nThe observation started on 2015-09-11 12:29:42 UT (~1.14 days after\nthe burst). We detected the previously reported afterglow (Pagani\net al., GCNC 18264; Zheng and Filippenko, GCNC 18265; Dichiara\net al., GCNC 18266; Kuroda et al., GCNC 18267) in g' and Rc bands.\n\nPhotometric results and three sigma upper limit of the OT are listed below.\nWe used GSC2.3 catalog for flux calibration.\n\n#T0+[day]  MID-UT    T-EXP[sec]   g'  g'_err  Rc  Rc_err  Ic  Ic_err                                                                    \n-----------------------------------------------------------------------\n1.21526    14:14:46    4800.0     21.8 0.2    21.2 0.2    >20.8\n-----------------------------------------------------------------------\nT0+ : Elapsed time after the burst [day]\nT-EXP: Total Exposure time [sec]",
