E. Berger (Princeton/OCIW) and R. Covarrubias (LCO) report:

"We observed the XRT error circle of GRB 071021 (GCNs 6963,6966) in the 
R-band using the LDSS3 instrument on the Magellan/Clay telescope.  In a 
coadded image of 540 sec we do not detect any objects within the XRT error 
circle to a 3-sigma limit of R>23.1 mag.  Further observations in R and I 
band are in progress."
