Jamie A. Kennea (PSU) reports on behalf of the Swift Team

GRB 230824A (GCN #34537) reported by Swift/BAT, previously triggered INTEGRAL at 12:20UT (Weak trigger #10373,0) 100 mins before the BAT trigger,  and continued to trigger INTEGRAL several times after the BAT trigger. Given this, and its location in the Galactic Bulge (l,b = 8.64, 10.241), we now believe this is a likely Galactic Transient and not a GRB.

We therefore rename this source Swift J1727.8-1613. Observations to confirm the nature of this transient are requested. Swift will not observe this transient until at least  August 27, 2023 due to the proximity of the Moon.
