SUBJECT: GRB 210815A: Fermi GBM Final Real-time Localization
DATE: 21/08/15 02:34:12 GMT
FROM: Fermi GBM Team at MSFC/Fermi-GBM
The Fermi GBM team reports the detection of a likely LONG GRB
At 02:23:49 UT on 15 Aug 2021, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 210815A (trigger 650687034.634966 / 210815100).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 351.8, Dec = -30.2 (J2000 degrees, equivalent to J2000 23h 27m, -30d 11'), with a statistical uncertainty of 2.9 degrees.
The angle from the Fermi LAT boresight is 98.0 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
650687034 at 02:23:49 on 15 Aug. 2021 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) = 347.5+/-2.7 deg
Decl.(2000.0) = -39.9+/-2.7 deg
We estimate an additional systematic error of 1 deg.
