The Fermi GBM team reports the detection of a likely LONG GRB
At 03:00:43 UT on 17 Nov 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 241117A (trigger 753505248.23077 / 241117125).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 2.0, Dec = 16.3 (J2000 degrees, equivalent to J2000 00h 08m, 16d 18'), with a statistical uncertainty of 1.7 degrees.
The angle from the Fermi LAT boresight is 58.0 degrees.
