The Fermi GBM team reports the detection of a likely LONG GRB
At 12:24:45 UT on 1 Dec 2022, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 221201A (trigger 691590290.314944 / 221201517).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 263.4, Dec = -70.4 (J2000 degrees, equivalent to J2000 17h 33m, -70d 24'), with a statistical uncertainty of 1.5 degrees.
The angle from the Fermi LAT boresight is 130.0 degrees.
