The Fermi GBM team reports the detection of a likely LONG GRB

At 12:44:22 UT on 22 Nov 2023, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 231122A (trigger 722349867.684022 / 231122531).

The on-ground calculated location, using the Fermi GBM trigger data, is RA = 108.4, Dec = -5.5 (J2000 degrees, equivalent to J2000 07h 13m, -5d 30'), with a statistical uncertainty of 3.8 degrees.

The angle from the Fermi LAT boresight is 87.0 degrees.
