GRB Location Alert
GRB 210826A: BALROG localization (Fermi Trigger 651654110 / GRB 210826293)
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
651654110 at 07:01:45 on 26 Aug. 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) = 84.3+/-5.4 deg
Decl.(2000.0) = -75.6+/-0.7 deg
We estimate an additional systematic error of 2 deg.
