The Fermi GBM team reports the detection of a likely SHORT GRB

"At 15:36:10.66 UT on 25 October 2024, the Fermi Gamma-ray Burst Monitor (GBM)
triggered and located GRB 241025C (trigger 751563375/241025650).

The on-ground calculated location, using the Fermi GBM trigger data,
is RA = 152.56, Dec = 48.27 (J2000 degrees, equivalent to J2000 10h 10m, +48d 16'),
with a statistical uncertainty of 2.29 degrees.

The angle from the Fermi LAT boresight is 75 degrees.
