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
575278303 at 07:31:39 on 26 March 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) = 261.4+/-9.0 deg
Decl.(2000.0) = 66.5+/-2.7 deg
We estimate an additional systematic error of 2 deg.

The SWIFT BAT detection of a short GRB at 07:35:28.72 UT was most likely a different GRB.
