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

At 02:23:16 UT on 1 Nov 2023, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 231101A (trigger 720498201.799648 / 231101099).

The on-ground calculated location, using the Fermi GBM trigger data, is RA = 137.1, Dec = 13.3 (J2000 degrees, equivalent to J2000 09h 08m, 13d 18'), with a statistical uncertainty of 13.2 degrees.

The angle from the Fermi LAT boresight is 86.0 degrees.
