FROM: Fermi GBM Team at MSFC/Fermi-GBM
The Fermi GBM team reports the detection of a likely LONG GRB
At 16:31:10 UT on 11 Apr 2021, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 210411D (trigger 639851475.876502 / 210411688).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 358.5, Dec = 24.3 (J2000 degrees, equivalent to J2000 23h 53m, 24d 18'), with a statistical uncertainty of 3.6 degrees.
The angle from the Fermi LAT boresight is 55.0 degrees.

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
at 16:31:10 on 11 Apr. 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) = 340.7+/-4.8 deg
Decl.(2000.0) = 36.6+/-3.2 deg
We estimate an additional systematic error of 2 deg.
