We have observed the field covering the error circle of
XRF101117A (MAXI trigger, GCN 11410, Yamazaki et al.)
with the unfiltered CCD camera on the 30-cm telescope
at University of Miyazaki.
The observation was started 18:16:09 UT (about 10.7 hr
after the MAXI trigger time) on the condition with a little cloud.
We have compared our data of 30 sec exposures with the USNO-A2.0 catalog.
There is no new source at the reported position.
