Foster report on\nbehalf of the UNC team of the FUN GRB Collaboration:\n\nUnder the control of Skynet, PROMPT observed the localization of GRB 051021\n(Yoshida et al., GCN 4116; Fox et al., GCN 4120) beginning 12.9 hours after\nthe burst, in Rc and Ic simultaneously.\n\nWe do not detect the afterglow of the burst.  In two 90 x 60 sec\nintegrations of mean epoch 14.2 hours after the burst, we measure 3-sigma\nlimiting magnitudes of Rc = 20.7 and Ic = 20.4 based on 5 USNO-B1.0 stars.\n\nPROMPT is still being built and commissioned.",
