Greiner (all MPE Garching) report:\n\nThe public trigdat data of the Fermi Gamma-ray Burst Monitor (GBM) trigger\n at 12:30:10 on 18 Oct. 2023 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 (1 sigma statistical errors) is:\nRA(2000.0) = 1.2+/-0.5 deg\nDecl.(2000.0) = 51.5+/-0.2 deg\nWe estimate an additional systematic error of 1 deg.\n\nFurther details are available at:\nhttps://grb.mpe.mpg.de/grb/GRB231018521/\n\nThe Healpix map can be downloaded from:\nhttps://grb.mpe.mpg.de/grb/GRB231018521/healpix\n\nThe location parameters are available as JSON at:\nhttps://grb.mpe.mpg.de/grb/GRB231018521/json\n\n                        \n",
