The Fermi GBM team reports the detection of a likely LONG GRB
At 08:38:11 UT on 24 Nov 2023, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 231124A (trigger 722507896.88707 / 231124360).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 237.5, Dec = 10.9 (J2000 degrees, equivalent to J2000 15h 50m, 10d 54'), with a statistical uncertainty of 2.1 degrees.
The angle from the Fermi LAT boresight is 79.0 degrees.
