on behalf of the MITSuME collaboration:
We observed GRB 121128A ( Oates et al., GCN Circular #14007) 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 was started on 2012-11-28 08:49:50 UT ( ~13453 sec
after the burst).
We detected the previously reported afterglow ( Oates et al., GCN
Circular #14007)
in Ic band. The results of photometry (3sigma upper limits) are listed below.
The photon flux were calibrated against GSC2.3 catalog.
