TITLE: GCN GRB OBSERVATION REPORT NUMBER: 3652 SUBJECT: GRB 050717: PROMPT RcIc Observations DATE: 05/07/21 00:18:08 GMT FROM: Daniel E. Reichart at U.North Carolina C. MacLeod, J. Kirschbrown, J. Haislip, M. Nysewander, J. A. Crain, D. Reichart report on behalf of the UNC team of the FUN GRB Collaboration: Under the control of Skynet, PROMPT automatically observed the refined XRT localization of GRB 050717 (Hurkett et al., GCN 3636) beginning 13.0 hours after the burst. We do not detect a source within this localization. 3-sigma limiting magnitudes are based on 5 USNO-B1.0 stars: Mean Time Integration Filter Limiting Telescope Since GRB Time Magnitude 13h 40m 58 x 80s Rc 21.7 PROMPT-5 16h 01m 70 x 80s Ic 21.5 PROMPT-5 PROMPT is still being built and commissioned.
