report on behalf of the MITSuME collaboration:
We have been observing the optical counterpart of GRB 161014A (J. L. Racusin et al., GCN
Circular #20035) with the optical three color (g', Rc, and Ic) CCD cameras attached to the MITSuME 50 cm
telescope of Akeno Observatory, Yamanashi, Japan.
The observation started on 2016-10-14 12:32:08 UT (46 sec after the burst) and
we detected the optical counterpart in all three bands.
The measured magnitudes were listed as follows.
We obtained following results for the magnitudes.
