TITLE: GCN CIRCULAR NUMBER: 43970 SUBJECT: GRB 260312B: BALROG localization (Fermi Trigger 795001611 / GRB 260312407) DATE: 26/03/12 10:16:35 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 795001611 at 09:46:46 on 12 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) = 26.3 deg Decl.(2000.0) = -8.3 deg The 1 sigma statistical error radius is 2.2 deg. We estimate an additional systematic error of 1 deg.
