We have observed the field covering the error circle of
GRB080229 (GCN 7338, C. Markwardt et al.) with
the unfiltered CCD camera on the 30-cm telescope at
University of Miyazaki.
The observation was started 17:05:03 UT, ~225 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.)
--------------------------------------------------------------
19:33:57 19:34:27 1 ~16.06
19:33:57 20:39:37 20 ~16.79
