GRB Location Alert
GRB 210524A: BALROG localization (Fermi Trigger 643525204 / GRB 210524208)
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
643525204 at 04:59:59 on 24 May 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) = 343.2+/-0.7 deg
Decl.(2000.0) = -47.2+/-0.4 deg
We estimate an additional systematic error of 2 deg.
