The Fermi GBM team reports the detection of a likely LONG GRB

At 22:13:08 UT on 5 Feb 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 240205B (trigger 728863993.169242 / 240205926).

The on-ground calculated location, using the Fermi GBM trigger data, is RA = 352.0, Dec = -53.0 (J2000 degrees, equivalent to J2000 23h 27m, -53d 00'), with a statistical uncertainty of 1.0 degrees.

The angle from the Fermi LAT boresight is 110.0 degrees.
