GRB 231030B: BALROG localization (Fermi Trigger 720388704 / GRB 231030832)
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
720388704 at 19:58:19 on 30 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) = 249.1+/-2.4 deg
Decl.(2000.0) = 63.3+/-0.9 deg
We estimate an additional systematic error of 2 deg.
