The Fermi GBM team reports the detection of a likely LONG GRB
At 00:30:44 UT on 7 Feb 2023, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 230207A (trigger 697422649.274452 / 230207021).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 234.3, Dec = -32.5 (J2000 degrees, equivalent to J2000 15h 37m, -32d 30'), with a statistical uncertainty of 4.9 degrees.
The angle from the Fermi LAT boresight is 82.0 degrees.
