We have observed the field covering the error circle of
GRB GRB091208A (Swift trigger 378554, GCN 10253Loading...
 
 , Hoversten et al.)
with the unfiltered CCD camera on the 30-cm telescope
at University of Miyazaki.
The observation was started 09:04:56 UT, about 19 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.)
--------------------------------------------------------------
09:04:56	09:05:26	 1	15.8
09:04:56	09:48:39	33	17.3
