D. W. Fox and P. A. Price (Caltech), with S. S. Eikenberry (Cornell),
report on behalf of a larger collaboration:

"We observed the HETE-II error circle for XRF011130 (GCN 1169) with
the Palomar Hale Telescope + Wide-Field Infrared Camera during an
instrument commissioning run on December 1.39 UT.  Preliminary
reduction of a subset of the data covering the location of the VLA
source at RA 03:05:24.71, Dec +3:46:13.1 (J2000; uncertainties 1.1" in
each coordinate; see GCN 1173) reveals no K'-band counterpart to a
limit of roughly K'=18.5 mag.  We note also the absence of any optical
counterpart to the VLA source in archival DPOSS images (limits of
approximately g=20.5 mag, r=20.7 mag, and i=20.3 mag) and in our Dec
1.24 UT NEAT images (limit of R=18.5 mag; see GCN 1170)."

D.W. Fox (Caltech) and P.A. Price (MSO/ANU), with S. Pravdo,
E. Helin, K. Lawrence, and M. Hicks of the NEAT/Palomar team, report
on behalf of the Caltech-NRAO-CARA GRB collaboration:

"We have observed the 10 arcmin-radius error circle of the XRF011130
(GCN 1169) with the 48-inch NEAT automated telescope on Mt. Palomar on
Dec 1.24 UT.  In unfavorable conditions of moon illumination and
seeing, we do not find any objects not present in DPOSS images of the
region.  We estimate the limiting magnitude of our images as R = 18.5
mag.  Further observations are planned."
