We have observed the field covering the error circle of
GRB09042 (Swift trigger 350854, GCN 9281, T. N. Ukwatta et al.)
with the unfiltered CCD camera on the 30-cm telescope
at University of Miyazaki.
The observation was started 11:29:13 UT, about 6.0 hr
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.
(GCN 9281, T. N. Ukwatta et al. GCN 9288, A.P. Beardmore et al.
 GCN 9290, M. Stamatikos et al.)

the upper limits are as follows:
--------------------------------------------------------------
Start(UT)   End(UT)    Num. of frames    Limit (mag.)
--------------------------------------------------------------
11:29:13    11:29:33          1            16.4
