TITLE: GCN CIRCULAR NUMBER: 43843 SUBJECT: GRB 260226A???: BALROG localization (Fermi Trigger 793795080 / GRB 260226443) DATE: 26/02/26 13:23:46 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 793795080 at 10:37:55 on 26 Feb. 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) = 43.6 deg Decl.(2000.0) = 9.6 deg The 1 sigma statistical error radius is 0.2 deg. We estimate an additional systematic error of 2 deg.
