GRB Location Alert

GRB 200125B: BALROG localization (Fermi Trigger 601677816 / GRB 200125864)

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
601677816 at 20:43:31 on 25 Jan. 2020 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) = 7.7+/-0.8 deg
Decl.(2000.0) = 64.4+/-0.4 deg
We estimate an additional systematic error of 2 deg.
