Nagayama (OAO, NAOJ) report on behalf of the MITSuME\ncollaboration:\n\nWe performed optical imaging observation of the field of GRB 081203A\n(Parsons, et al., GCN Circ. 8595) with the 3-color 50cm MITSuME\nTelescopes at Akeno Observatory and Okayama Astrophysical Observatory\nfrom UT 17:50 to UT 20:55, 3.9 hours after the trigger.\n\nIn the co-added images of Rc, and g' bands, we detected the optical\nafterglow detected with UVOT (Parsons, et al., GCN Circ. 8595).\nPhotometric calibration was done using the GSC2.3 catalogs.\nThe results are following:\n\nAkeno:\nMID-MJD      MID-UT    EXP-T        g'            Rc\n----------------------------------------------------------\n54803.753779 18:12:54  1620.0  18.50+/-0.24  18.11+/-0.25\n----------------------------------------------------------\n\nOkayama:\nMID-MJD      MID-UT    EXP-T        g'            Rc\n----------------------------------------------------------\n54803.790960 18:58:59  1500.0  18.87+/-0.26  18.36+/-0.19\n54803.811830 19:29:03  1500.0  19.18+/-0.25  17.89+/-0.15\n54803.833037 19:59:35  1560.0  19.11+/-0.23  18.49+/-0.24\n54803.854522 20:30:31  1560.0  19.63+/-0.32  18.91+/-0.19\n----------------------------------------------------------",
