report on behalf of the MITSuME collaboration:

We searched for the optical counterpart of GRB 161014A (J. L. Racusin et
al., GCN Circular #20035Not found
 
 
) 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).
We found a candidate afterglow in the BAT error circle (J. L. Racusin,
GCNCircular
#20035), at
RA(J2000) = 22:10:35.47
Dec(J2000) = +07:28:07.6
with an uncertainty of ~0.4 arcsec.

 We obtained the following magnitude in Rc band.
