We have observed the field covering the error circle of
GRB070419A (GCN 6302, M. Stamatikos et al.) with
the unfiltered CCD camera on the 30-cm telescope at
University of Miyazaki.
The observation was started 10:24:34 UT, ~25 min
after the Swift trigger time.
We have compared our data of 30 sec exposures
with the USNO-A2.0 catalog,
the upper limits are as follows:
--------------------------------------------------------------
Start(UT) End(UT) Num. of frames Limit (mag.)
--------------------------------------------------------------
10:42:40 10:43:10 1 ~16.2
10:42:40 10:53:36 10 ~17.7
