SUBJECT: GRB 190923A: Fermi GBM Final Real-time Localization
DATE: 19/09/23 14:58:21 GMT
FROM: Fermi GBM Team at MSFC/Fermi-GBM
The Fermi GBM team reports the detection of a likely LONG GRB
At 14:48:02 UT on 23 Sep 2019, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 190923A (trigger 590942887.75117 / 190923617).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 8.2, Dec = -11.0 (J2000 degrees, equivalent to J2000 00h 32m, -11d 00'), with a statistical uncertainty of 4.9 degrees.
The angle from the Fermi LAT boresight is 43.0 degrees.

SUBJECT: GRB 190923A: BALROG localization (Fermi Trigger 590942887 / GRB 190923617)
DATE: 19/09/23 15:09:00 GMT
FROM: Jochen Greiner at MPE,Garching
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
590942887 at 14:48:02 on 23 Sept. 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) = 5.9+/-1.6 deg
Decl.(2000.0) = -14.0+/-1.3 deg
We estimate an additional systematic error of 1 deg.
