TITLE: GCN GRB OBSERVATION REPORT NUMBER: 3670 SUBJECT: GRB 050724: Swift/UVOT Upper Limit DATE: 05/07/24 21:10:45 GMT FROM: Margaret Chester at PSU M. Chester (PSU), S. Covino (OAB), P. Schady (MSSL), P. Roming (PSU) N. Gehrels (GSFC), on behalf of the Swift UVOT team. Using summed images from Swift/UVOT of the field of GRB 050724 (Covino et al., GCN 3665), accumulated during the first forty minutes after the BAT trigger, no new source is detected within the XRT error circle in the V filter down to a 3-sigma limit of V=18.84. The magnitudes are based on preliminary zero-points, measured in orbit, and will require refinement with further calibration.
