We have observed the field covering the error circle of GRB GRB 090206A (Swift trigger 411412, GCN 10376, Krimm et al.) with the unfiltered CCD camera on the 30-cm telescope at University of Miyazaki. The observation was started 13:31:14 UT, about 1 min after the Swift trigger time. We have compared our data of 30 sec exposures with the USNO-A2.0 catalog, There is no new source at the reported position. the upper limits are as follows: -------------------------------------------------------------- Start(UT) End(UT) Num. of frames Limit (mag.) -------------------------------------------------------------- 13:31:14 13:31:44 1 14.1 13:31:14 14:26:55 29 17.4 ---------------------------------------------------------------
