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

At 10:57:02 UT on 16 Feb 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 240216A (trigger 729773827.851682 / 240216456).

The on-ground calculated location, using the Fermi GBM trigger data, is RA = 34.1, Dec = -75.9 (J2000 degrees, equivalent to J2000 02h 16m, -75d 54'), with a statistical uncertainty of 5.1 degrees.

The angle from the Fermi LAT boresight is 43.0 degrees.
