The Fermi GBM team reports the detection of a likely LONG GRB
At 15:07:38 UT on 4 Feb 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 240204A (trigger 728752063.677018 / 240204630).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 101.5, Dec = -3.4 (J2000 degrees, equivalent to J2000 06h 46m, -3d 23'), with a statistical uncertainty of 1.6 degrees.
The angle from the Fermi LAT boresight is 102.0 degrees.
