report on behalf of the MITSuME collaboration:
We observed the field of GRB 140629A (A. Y. Lien et al., GCN Circular #16477) 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 2014-06-29 14:23:32 UT (6 min after the burst).
We detected the previously reported optical afterglow of GRB140629A
(V.Yurkov et al., GCN Circular #16478) in the g', Rc and Ic band.
The measured magnitudes are listed below.
