report on behalf of the MITSuME and OISTER collaboration:
We observed the field of GRB 141031B (Gompertz et al., GCNC 16998)
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 2014-10-31 15:02:03 (~5.3 min after the burst).
We did not find any new point source within the enhanced XRT circle
(Osborne et al., GCNC 17009) in all the three bands.
Three sigma upper limits of the OT are listed below.
We used SDSS catalog for flux calibration.
