GRB 231020A: BALROG localization (Fermi Trigger / GRB 231020790)
T. Preis, B. Biltzinger, J. Burgess & J. Greiner (all MPE Garching) report:
The public trigdat data of the Fermi Gamma-ray Burst Monitor (GBM) trigger
at 18:56:58 on 20 Oct. 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) = 316.0+/-0.4 deg
Decl.(2000.0) = -31.3+/-0.3 deg
We estimate an additional systematic error of 2 deg.
