GRB Location Alert
GRB 191225B: BALROG localization (Fermi Trigger 598988276 / GRB 191225735)
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
598988276 at 17:37:51 on 25 Dec. 2019 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) = 144.1+/-1.7 deg
Decl.(2000.0) = -7.2+/-0.8 deg
We estimate an additional systematic error of 2 deg.
