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

At 07:32:40.63 UT on 25 June 2024, the Fermi Gamma-ray Burst Monitor (GBM)
triggered and located GRB 240625A (trigger 740993565/240625314).

The on-ground calculated location, using the Fermi GBM trigger data,
is RA = 118.74, Dec = -4.94 (J2000 degrees, equivalent to J2000 7h 54m, -4d 56'),
with a statistical uncertainty of 9.43 degrees.

The angle from the Fermi LAT boresight is 66 degrees.
