GRB Location Alert
GRB 220304A: BALROG localization (Fermi Trigger / GRB 220304228)
B. Biltzinger, F. Kunzweiler, F. Berlato, J. Burgess & J. Greiner (all MPE Garching) report:
The public trigdat data of the Fermi Gamma-ray Burst Monitor (GBM) trigger
at 05:28:58 on 04 March 2022 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) = 249.0+/-0.6 deg
Decl.(2000.0) = -37.9+/-0.3 deg
We estimate an additional systematic error of 1 deg.
