S. Dichiara (PSU), P. A. Evans (U Leicester) and
K. L. Page (U Leicester) report on behalf of the Neil Gehrels Swift
Observatory Team:

At 09:03:36 UT, the Swift Burst Alert Telescope (BAT) triggered and located
Swift J1727.8-1613 (trigger number 1187142); this is the third BAT trigger on
this event (GCN Circ. 34537; GCN Circ. 34542) which remains unobservable with
XRT and UVOT until 09:35 UT on 2023 August 27; however, MAXI have reported a
very bright (>2 Crab) 10-20 keV X-ray counterpart. This object is believed to be
a Galactic transient, Swift J1727.8-1613 (GCN Circ. 34540).
