report on behalf of the MITSuME collaboration:
We observed the field of GRB 141015A (E. Troja et al., GCN Circular #16909) 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 2014-10-15 14:40:07 UT (~5.5 h after the burst).
We did not find any new point source within the enhanced XRT circle
(P. A. Evans et al., GCN Circular #16913) in all the three bands.
The measured magnitudes are listed below.
