Greiner (MPE Garching) report:\n\nThe public trigdat data of the Fermi Gamma-ray Burst Monitor (GBM) trigger\n779223130 at 18:52:05 on 10 Sept. 2025 were automatically fitted for spectrum\nand sky location with BALROG (Burgess et al. 2018, MNRAS 476, 1427;\nBerlato et al. 2019, ApJ 873, 60).\n\nThe best-fit position is:\nRA(2000.0) = 74.2 deg\nDecl.(2000.0) = -47.5 deg\nThe 1 sigma statistical error radius is 3.6 deg.\nWe estimate an additional systematic error of 1 deg.\n\nFurther details are available at:\nhttps://grb.mpe.mpg.de/grb/GRB250910786/\n\nThe Healpix map can be downloaded from:\nhttps://grb.mpe.mpg.de/grb/GRB250910786/healpix\n\nThe location parameters are available as JSON at:\nhttps://grb.mpe.mpg.de/grb/GRB250910786/json\n\n                        \n"
