GRB Location Alert
GRB 220107A: BALROG localization (Fermi Trigger 663259536 / GRB 220107615)
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
663259536 at 14:45:31 on 07 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) = 168.5+/-1.4 deg
Decl.(2000.0) = 34.9+/-1.0 deg
We estimate an additional systematic error of 2 deg.
