The Fermi GBM team reports the detection of a likely LONG GRB
At 15:06:46 UT on 5 Apr 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 240405A (trigger 734022411.49845 / 240405630).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 289.6, Dec = 37.8 (J2000 degrees, equivalent to J2000 19h 18m, 37d 47'), with a statistical uncertainty of 5.2 degrees.
The angle from the Fermi LAT boresight is 143.0 degrees.
