"We have observed the field covering the error box of
GRB 040422 (INTEGRAL trigger 1758; trigger time 07:45:27 UT) with the
unfiltered CCD camera on the 30-cm telescope at University of
Miyazaki.The observation was started 14:06:55 UT on Apl.22.
Observed field of view is 43 arcmin centerd on R.A=18,41,38
Dec=+02,04,20d.
After co-adding a set of 2 images of 30 sec exposures ,
we have compared with the USNO A2.0 catalog . Preliminary analysis
shows there is no new source brighter than 16.94 mag.
in the GRB error box reported by INTEGRAL. "
