TITLE: GCN CIRCULAR NUMBER: 45287 SUBJECT: GRB 260805B: BALROG localization (Fermi Trigger 807622617 / GRB 260805484) DATE: 26/08/05 12:19:46 GMT FROM: Jochen Greiner at MPE <jcgrog@mpe.mpg.de> T. Preis (University of Innsbruck) & J. Greiner (MPE Garching) report: The public trigdat data of the Fermi Gamma-ray Burst Monitor (GBM) trigger 807622617 at 11:36:52 on 05 Aug. 2026 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 is: RA(2000.0) = 255.8 deg Decl.(2000.0) = 67.9 deg The 1 sigma statistical error radius is 2.9 deg. We estimate an additional systematic error of 2 deg.
