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

At 23:44:04 UT on 2 Apr 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 240402A (trigger 733794249.222788 / 240402989).

The on-ground calculated location, using the Fermi GBM trigger data, is RA = 220.9, Dec = 29.3 (J2000 degrees, equivalent to J2000 14h 43m, 29d 18'), with a statistical uncertainty of 25.0 degrees.

The angle from the Fermi LAT boresight is 98.0 degrees.
