R. Cummings et al.) \nwith the unfiltered CCD camera on the 30-cm telescope \nat University of Miyazaki.\nThe observation was started 12:50:29 UT (1.7 min. after the Swift trigger), \nunder cloudy condition.\nFirst analyzable image was obtained at 12:57:06 UT (6.5 min. after the Swift trigger). \n\nWe have compared our data of 30 sec exposures\nwith the USNO-A2.0 catalog,\nThere is no new source at the reported position.\n(GCN 9254, J.
