TITLE: GCN CIRCULAR NUMBER: 6657 SUBJECT: Short-Hard GRB070714B: PROMPT Observations DATE: 07/07/24 15:35:26 GMT FROM: Christine Weaver at FUNGRB/PROMPT C. Weaver, T. Brennan, M. Schubel, J. Styblova, J. Haislip, D. Reichart, M. Nysewander, A. LaCluyze, K. Ivarsen, J. A. Crain, A. Foster, and A. Trotter 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.
