TITLE: GCN CIRCULAR NUMBER: 34542 SUBJECT: Trigger 1186982: Swift detection of Swift J1727.8-1613 (AKA GRB 230824A) DATE: 23/08/24 19:09:08 GMT FROM: K.L. Page at U Leicester S. Dichiara (PSU), J. A. Kennea (PSU), K. L. Page (U Leicester), T. M. Parsotan (GSFC/UMBC/CRESSTII) and M. A. Williams (PSU) report on behalf of the Neil Gehrels Swift Observatory Team: At 18:54:32 UT, the Swift Burst Alert Telescope (BAT) triggered and located Swift J1727.8-1613. Due to a Moon observing constraint, Swift cannot observe this location until 09:35 UT on 2023 August 27. We note this is the 2nd time BAT has triggered on this source, previously named GRB 230824A (GCN #34537), now likely a Galactic transient Swift J1727.8-1613 (GCN #34540)
