GRB Location Alert
GRB 220111A: BALROG localization (Fermi Trigger 663621714 / GRB 220111807)
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
663621714 at 19:21:49 on 11 Jan. 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) = 149.9+/-0.9 deg
Decl.(2000.0) = 0.6+/-0.8 deg
We estimate an additional systematic error of 1 deg.
