report on behalf of the MITSuME and OISTER collaboration:
We observed the field of GRB 150910A (Pagani et al., GCNC 18264)
with the optical three color (g', Rc and Ic) CCD camera attached
to the Murikabushi 1m telescope of Ishigakijima Astronomical
Observatory.
The observation started on 2015-09-11 12:29:42 UT (~1.14 days after
the burst). We detected the previously reported afterglow (Pagani
et al., GCNC 18264; Zheng and Filippenko, GCNC 18265; Dichiara
et al., GCNC 18266; Kuroda et al., GCNC 18267) in g' and Rc bands.
Photometric results and three sigma upper limit of the OT are listed below.
We used GSC2.3 catalog for flux calibration.
