GRB Location Alert
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
581026217 at 20:10:12 on 31 May 2019 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) = 27.9+/-0.8 deg
Decl.(2000.0) = -40.8+/-0.6 deg
We estimate an additional systematic error of 2 deg.
Further details are available at:

The Healpix map can be downloaded from:
