GRB Location Alert
GRB 221209A: BALROG localization (Fermi Trigger 692257829 / GRB 221209243)
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
692257829 at 05:50:24 on 09 Dec. 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) = 234.9+/-0.9 deg
Decl.(2000.0) = 48.7+/-0.6 deg
We estimate an additional systematic error of 2 deg.
