SUBJECT: GRB 190808B: Fermi GBM Final Real-time Localization
DATE: 19/08/08 18:13:38 GMT
FROM: Fermi GBM Team at MSFC/Fermi-GBM
The Fermi GBM team reports the detection of a likely LONG GRB
At 18:03:17 UT on 8 Aug 2019, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 190808B (trigger 586980202.431972 / 190808752).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 168.1, Dec = 39.7 (J2000 degrees, equivalent to J2000 11h 12m, 39d 42'), with a statistical uncertainty of 1.4 degrees.
The angle from the Fermi LAT boresight is 72.0 degrees.

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
586980202 at 18:03:17 on 08 Aug. 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) = 168.0+/-1.3 deg
Decl.(2000.0) = 36.1+/-1.5 deg
We estimate an additional systematic error of 1 deg.
