The Fermi GBM team reports the detection of a likely LONG GRB
At 18:34:20 UT on 30 Oct 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 241030B (trigger 752006065.391554 / 241030774).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 52.7, Dec = 36.0 (J2000 degrees, equivalent to J2000 03h 30m, 36d 00'), with a statistical uncertainty of 3.0 degrees.
The angle from the Fermi LAT boresight is 52.0 degrees.
