GRB Location Alert
GRB 210207A: BALROG localization (Fermi Trigger / GRB 210207603)
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
at 14:27:58 on 07 Feb. 2021 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) = 145.7+/-2.6 deg
Decl.(2000.0) = -1.4+/-2.6 deg
We estimate an additional systematic error of 1 deg.
