The Fermi GBM team reports the detection of a likely LONG GRB.
At 11:19:44.36 UT on 4 Nov 2022, the Fermi Gamma-ray Burst Monitor (GBM)
triggered and located GRB 221104A (trigger 689253589 / 221104472).
The on-ground calculated location, using the Fermi GBM trigger data, is
RA = 180.2, Dec = -22.7
(J2000 degrees, equivalent to J2000 12h 01m, -22d 42'), with a
statistical uncertainty of 11.7 degrees.
The angle from the Fermi LAT boresight is 101 degrees.
