The Fermi GBM team reports the detection of a likely LONG GRB
"At 13:06:36.09 UT on 25 October 2024, the Fermi Gamma-ray Burst Monitor (GBM)
triggered and located GRB 241025B (trigger 751554401/241025546).
The on-ground calculated location, using the Fermi GBM trigger data,
is RA = 254.69, Dec = 9.07 (J2000 degrees, equivalent to J2000 16h 58m, +9d 4'),
with a statistical uncertainty of 2.53 degrees.
The angle from the Fermi LAT boresight is 89 degrees.
