The Fermi GBM team reports the detection of a likely LONG GRB
At 02:16:38 UT on 1 Jan 2023, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 230101A (trigger 694232203.998664 / 230101095).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 206.3, Dec = -21.9 (J2000 degrees, equivalent to J2000 13h 45m, -21d 53'), with a statistical uncertainty of 2.8 degrees.
The angle from the Fermi LAT boresight is 49.0 degrees.
