Circular_text TITLE: GCN CIRCULAR NUMBER: 34422 SUBJECT: GRB 230814A: Fermi GBM Final Real-time Localization DATE: 23/08/14 19:05:27 GMT FROM: Fermi GBM Team at MSFC/Fermi-GBM The Fermi GBM team reports the detection of a likely LONG GRB At 18:54:56 UT on 14 Aug 2023, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 230814A (trigger 713732101.037422 / 230814788). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 288.8, Dec = -14.2 (J2000 degrees, equivalent to J2000 19h 15m, -14d 11'), with a statistical uncertainty of 4.0 degrees. The angle from the Fermi LAT boresight is 100.0 degrees.

Circular_text TITLE: GCN CIRCULAR NUMBER: 34424 SUBJECT: GRB 230814A: BALROG localization (Fermi Trigger 713732101 / GRB 230814788) DATE: 23/08/14 19:28:45 GMT FROM: Jochen Greiner at MPE B. Biltzinger, T. Preis, J. Burgess & J. Greiner (all MPE Garching) report: The public trigdat data of the Fermi Gamma-ray Burst Monitor (GBM) trigger 713732101 at 18:54:56 on 14 Aug. 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) = 288.4+/-1.2 deg Decl.(2000.0) = -12.0+/-1.3 deg We estimate an additional systematic error of 1 deg.
