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

At 05:12:52 UT on 4 May 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 240504A (trigger 736492377.637702 / 240504217).

The on-ground calculated location, using the Fermi GBM trigger data, is RA = 64.6, Dec = -8.7 (J2000 degrees, equivalent to J2000 04h 18m, -8d 41'), with a statistical uncertainty of 2.4 degrees.

The angle from the Fermi LAT boresight is 64.0 degrees.
