Goad et al.) with\nthe unfiltered CCD camera on the 30-cm telescope at\nUniversity of Miyazaki.\nThe observation was started 11:25:17 UT,\nbut it was cloudy then,so we got first image at 13:44:43 UT, ~141 min\nafter the Swift trigger time.\n\nWe have compared our data of 30 sec exposures\nwith the USNO-A2.0 catalog,there is no new source\nat the reported position (GCN 7369, N. R. Tanvir)\n\n\nthe upper limits are as follows:\n--------------------------------------------------------------\nStart(UT) End(UT)\tNum. of frames \tLimit (mag.)\n--------------------------------------------------------------\n14:01:59 14:02:29 \t1 \t\t~16.36\n14:01:59 17:26:12 \t20 \t\t~16.99\n---------------------------------------------------------------",
