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

At 18:13:23 UT on 6 Nov 2023, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 231106A (trigger 720987208.394416 / 231106759).

The on-ground calculated location, using the Fermi GBM trigger data, is RA = 113.8, Dec = 25.6 (J2000 degrees, equivalent to J2000 07h 35m, 25d 36'), with a statistical uncertainty of 3.4 degrees.

The angle from the Fermi LAT boresight is 120.0 degrees.
