Circular_text TITLE: GCN CIRCULAR NUMBER: 34108 SUBJECT: GRB 230628D: Fermi GBM Final Real-time Localization DATE: 23/06/28 20:32:52 GMT FROM: Fermi GBM Team at MSFC/Fermi-GBM The Fermi GBM team reports the detection of a likely LONG GRB At 20:22:31 UT on 28 Jun 2023, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 230628D (trigger 709676556.5632 / 230628849). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 175.0, Dec = 12.3 (J2000 degrees, equivalent to J2000 11h 39m, 12d 18'), with a statistical uncertainty of 1.6 degrees. The angle from the Fermi LAT boresight is 25.0 degrees.

Circular_text TITLE: GCN CIRCULAR NUMBER: 34109 SUBJECT: GRB 230628D: BALROG localization (Fermi Trigger 709676556 / GRB 230628849) DATE: 23/06/28 20:54:04 GMT FROM: Jochen Greiner at MPE T. Preis, B. Biltzinger, J. Burgess & J. Greiner (all MPE Garching) report: The public trigdat data of the Fermi Gamma-ray Burst Monitor (GBM) trigger 709676556 at 20:22:31 on 28 June 2023 were automatically fitted for spectrum and sky location with BALROG (Burgess et al. 2018, MNRAS 476, 1427; Berlato et al. 2019, ApJ 873, 60). The best-fit position (1 sigma statistical errors) is: RA(2000.0) = 177.0+/-1.2 deg Decl.(2000.0) = 3.0+/-1.1 deg We estimate an additional systematic error of 2 deg.
