GRB 260226A???: BALROG localization (Fermi Trigger 793795080 / GRB 260226443)

T. Preis (University of Innsbruck) & J. Greiner (MPE Garching) report:

The public trigdat data of the Fermi Gamma-ray Burst Monitor (GBM) trigger
793795080 at 10:37:55 on 26 Feb. 2026 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 is:
RA(2000.0) = 43.6 deg
Decl.(2000.0) = 9.6 deg
The 1 sigma statistical error radius is 0.2 deg.
We estimate an additional systematic error of 2 deg.
