report:

Skynet observed the localization of short-hard GRB 070714B (Racusin et al., 
GCN 6620) with two of the 16" PROMPT telescopes at CTIO beginning 4.5 hours 
after the burst in UBV.

We do not detect the afterglow (Melandri et al., GCN 6621) to 3-sigma 
limiting magnitudes of B = 19.9 mag at a mean time of 4.9 hours after the 
burst (13 x 80 sec, calibrated to 14 USNO B1.0 stars) and V = 19.8 mag at a 
mean time of 5.5 hours after the burst (20 x 80 sec, calibrated to 13 NOMAD 
stars.
