GRB Location Alert
GRB 220525A: BALROG localization (Fermi Trigger 675130259 / GRB 220525008)
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
675130259 at 00:10:54 on 25 May. 2022 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) = 10.61+/-1.03 deg
Decl.(2000.0) = 15.31+/-0.70 deg
We estimate an additional systematic error of 1 deg.
