TITLE: GCN CIRCULAR NUMBER: 14920 SUBJECT: Swift Trigger 558828 is not an interesting event DATE: 13/06/23 09:16:07 GMT FROM: David Palmer at LANL D. Malesani (DARK/NBI), D. M. Palmer (LANL) and M. H. Siegel (PSU) report on behalf of the Swift Team: Due to a known race condition in the Swift software, an image peak was misidentified as a rarely-seen source. It was, however, correctly identified on the ground as 4U 1700-377, at a flux level that is often seen for this source. Thus this detection is not an interesting event.
