The Fermi GBM team reports the detection of a likely LONG GRB
At 01:36:26 UT on 25 Oct 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 241025A (trigger 751512991.890046 / 241025067).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 326.2, Dec = 80.3 (J2000 degrees, equivalent to J2000 21h 44m, 80d 17'), with a statistical uncertainty of 3.6 degrees.
The angle from the Fermi LAT boresight is 46.0 degrees.
