GRB Location Alert

GRB 200402B: BALROG localization (Fermi Trigger 607537834 / GRB 200402688)

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
607537834 at 16:30:29 on 02 April 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) = 193.9+/-2.2 deg
Decl.(2000.0) = -10.1+/-2.7 deg
We estimate an additional systematic error of 1 deg.
