GRB Location Alert
GRB 210324C: BALROG localization (Fermi Trigger 638308803 / GRB 210324833)
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
638308803 at 19:59:58 on 24 March 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) = 43.2+/-0.6 deg
Decl.(2000.0) = -48.1+/-0.5 deg
We estimate an additional systematic error of 2 deg.
