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
625859489 at 17:51:24 on 31 Oct. 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) = 48.1+/-8.6 deg
Decl.(2000.0) = 60.7+/-7.4 deg
We estimate an additional systematic error of 2 deg.

The Healpix map can be downloaded from:
