GRB 230904B: BALROG localization (Fermi Trigger 715526984 / GRB 230904562)
Abstract
The public trigdat data of the Fermi Gamma-ray Burst Monitor (GBM) trigger 715526984 at 13:29:39 on 04 Sept. 2023 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 (1 sigma statistical errors) is: RA(2000.0) = 20.8+/-2.4 deg Decl.(2000.0) = -26.7+/-0.9 deg We estimate an additional systematic error of 2 deg.
