GRB 230308A: BALROG localization (Fermi Trigger 699975152 / GRB 230308564)
Abstract
The public trigdat data of the Fermi Gamma-ray Burst Monitor (GBM) trigger 699975152 at 13:32:27 on 08 March 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) = 104.5+/-7.6 deg Decl.(2000.0) = 67.3+/-1.3 deg We estimate an additional systematic error of 2 deg.
