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
618851447 at 15:10:42 on 11 Aug. 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) = 122.2+/-1.8 deg
Decl.(2000.0) = -4.9+/-1.8 deg
We estimate an additional systematic error of 1 deg.

DATE: 20/08/11 17:38:58 GMT
FROM: Joshua Wood at MSFC/Fermi-GBM
The Fermi GBM team reports the detection of a likely LONG GRB
At 15:10:42 UT on 11 Aug 2020, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 200811A (trigger 618851447 / 200811632).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 120.2, Dec = -4.80 (J2000 degrees, equivalent to J2000 8h 1m, -4d 48'), with a statistical uncertainty of 1.7 degrees.
The angle from the Fermi LAT boresight is 60.0 degrees.
