GRB 230321A: BALROG localization (Fermi Trigger 701065308 / GRB 230321182)


F. Kunzweiler, B. Biltzinger, F. Berlato, J. Burgess & J. Greiner (all MPE Garching) report:

The public trigdat data of the Fermi Gamma-ray Burst Monitor (GBM) trigger
701065308 at 04:21:43 on 21 Mar. 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) = 65.24+/-1.54 deg
Decl.(2000.0) = 31.70+/-1.26 deg
We estimate an additional systematic error of 2 deg.
