report on behalf of the MITSuME collaboration:
We observed the field of GRB 140508A (H.Yu et al., GCN Circular #16224) 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 2014-05-09 11:07:31 UT (32.1h after the burst).
We detected the optical afterglow of GRB140508A in the g',Rc and Ic band.
The measured magnitudes were listed below.
