The Fermi GBM team reports the detection of a likely LONG GRB
At 01:02:12 UT on 8 Apr 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 240408A (trigger 734230937.764604 / 240408043).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 353.5, Dec = 50.1 (J2000 degrees, equivalent to J2000 23h 33m, 50d 06'), with a statistical uncertainty of 13.4 degrees.
The angle from the Fermi LAT boresight is 32.0 degrees.
