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

At 06:18:04 UT on 12 Nov 2022, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 221112A (trigger 689926689.355394 / 221112263).

The on-ground calculated location, using the Fermi GBM trigger data, is RA = 91.8, Dec = -52.6 (J2000 degrees, equivalent to J2000 06h 07m, -52d 36'), with a statistical uncertainty of 5.7 degrees.

The angle from the Fermi LAT boresight is 41.0 degrees.
