TITLE: GCN CIRCULAR NUMBER: 43908 SUBJECT: GRB 260303B: BALROG localization (Fermi Trigger 794237065 / GRB 260303559) DATE: 26/03/03 14:05:07 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 794237065 at 13:24:20 on 03 March 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) = 13.0 deg Decl.(2000.0) = -27.8 deg The 1 sigma statistical error radius is 1.3 deg. We estimate an additional systematic error of 1 deg.
