GCN 9430)\nwith optical three color (g', Rc and Ic) CCD camera attached to\nthe MITSuME 50cm telescope of Okayama Astrophysical Observatory.\nThe observation started on 2009-05-29 14:51:47 UT. We found a\nfaint source at the UVOT position reported by Schady et al. (GCN\n9435) in g' band.\n\nPhotometric results are listed below. We used USNO B1 catalog\nfor flux calibration.\n\n#PDAY      MID-UT   T-EXP     g'   g'_err     Rc      Ic\n----------------------------------------------------------\n0.03564  15:03:55  1200sec   20.3   0.4     >19.7   >18.9\n----------------------------------------------------------",
