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

At 06:26:57 UT on 15 Apr 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 240415A (trigger 734855222.604114 / 240415269).

The on-ground calculated location, using the Fermi GBM trigger data, is RA = 201.6, Dec = 75.7 (J2000 degrees, equivalent to J2000 13h 26m, 75d 42'), with a statistical uncertainty of 8.2 degrees.

The angle from the Fermi LAT boresight is 110.0 degrees.
