E. Berger (Princeton/OCIW) and S. Gonzalez (LCO) report:

"We observed the XRT error circle of GRB 071117 (GCNs 7102,7103) with the 
Swope 40-inch telescope at LCO starting on 2007 Nov. 18.07 UT (10.8 hours 
after the burst).  In a single 300 sec exposure we do not detect any 
source within the XRT error circle to a limit of i>21 mag."
