TITLE: GCN CIRCULAR NUMBER: 21305 SUBJECT: Trigger 760835: Swift misidentification of GRS1716-249 DATE: 17/07/08 03:15:52 GMT FROM: David Palmer at LANL A. Cholden-Brown (PSU), J. A. Kennea (PSU), A. Y. Lien (GSFC/UMBC), K. L. Page (U Leicester) and D. M. Palmer (LANL) report on behalf of the Swift Team: For an image beginning at 03:34:04 UT, BAT misidentified the known source GRS 1716-249 as a different source and incorrectly triggered an alert. This is due to a known race condition in the onboard software. The flux level of GRS 1716-249 in this detection is consistent with recent observations of this source, which has been in outburst since December 2016 and has declined to ~40% of its peak value.
