The Fermi GBM team reports the detection of a likely LONG GRB
At 21:44:54 UT on 24 Sep 2022, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 220924A (trigger 685748699.41428 / 220924906).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 321.5, Dec = 33.8 (J2000 degrees, equivalent to J2000 21h 26m, 33d 47'), with a statistical uncertainty of 5.2 degrees.
The angle from the Fermi LAT boresight is 91.0 degrees.
