GRB Location Alert
GRB 200228A: BALROG localization (Fermi Trigger 604565918 / GRB 200228291)
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
604565918 at 06:58:33 on 28 Feb. 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) = 332.9+/-0.9 deg
Decl.(2000.0) = -39.9+/-1.0 deg
We estimate an additional systematic error of 1 deg.
