Reichart report on behalf of the UNC team of the FUN GRB Collaboration: Under the control of Skynet, PROMPT observed the localization of GRB 050726 (Barthelmy et al., GCN 3582) beginning 18.5 hours after the burst in Rc (Haislip et al., GCN 3687). We do not detect any new sources within or around the XRT localization. 3-sigma limiting magnitudes are based on 3 USNO-B1.0 stars: Mean Time Integration Filter Limiting Telescope Since GRB Time Magnitude 19h 46m 205 x 40s Rc 22.2 PROMPT-5 PROMPT is still being built and commissioned.
