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

At 01:44:58 UT on 11 Apr 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 240411A (trigger 734492703.48149 / 240411073).

The on-ground calculated location, using the Fermi GBM trigger data, is RA = 242.6, Dec = 40.6 (J2000 degrees, equivalent to J2000 16h 10m, 40d 36'), with a statistical uncertainty of 5.4 degrees.

The angle from the Fermi LAT boresight is 64.0 degrees.
