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

At 00:59:51 UT on 7 Apr 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 240407A (trigger 734144396.810938 / 240407042).

The on-ground calculated location, using the Fermi GBM trigger data, is RA = 352.3, Dec = 44.9 (J2000 degrees, equivalent to J2000 23h 29m, 44d 53'), with a statistical uncertainty of 1.7 degrees.

The angle from the Fermi LAT boresight is 88.0 degrees.
