M. Nysewander, C. Macleod, D. Reichart, A. Crain, A. Foster report on
behalf of the UNC team of the FUN GRB Collaboration:
Under the control of Skynet, PROMPT observed the localization of GRB 051021
(Yoshida et al., GCN 4116; Fox et al., GCN 4120) beginning 12.9 hours after
the burst, in Rc and Ic simultaneously.
We do not detect the afterglow of the burst. In two 90 x 60 sec
integrations of mean epoch 14.2 hours after the burst, we measure 3-sigma
limiting magnitudes of Rc = 20.7 and Ic = 20.4 based on 5 USNO-B1.0 stars.
PROMPT is still being built and commissioned.
