We have observed the field covering the error circle of
GRB080328 (GCN 7527, A.P. Beardmore et al.) with
the unfiltered CCD camera on the 30-cm telescope at
University of Miyazaki.
The observation was started 11:09:32 UT; about 186 minutes
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.)
--------------------------------------------------------------
11:10:49 11:11:07 1 ~15.74
11:10:59 12:58:24 65 ~17.70
