GRB Location Alert

GRB 200101A: BALROG localization (Fermi Trigger 599603971 / GRB 200101861)

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
599603971 at 20:39:26 on 01 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) = 259.1+/-0.4 deg
Decl.(2000.0) = -32.7+/-0.4 deg
We estimate an additional systematic error of 1 deg.
