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

"At 20:48:42.61 UT on 25 January 2024, the Fermi Gamma-ray Burst Monitor (GBM)
triggered and located GRB 240125B (trigger 727908527/240125867).

The on-ground calculated location, using the Fermi GBM trigger data,
is RA = 81.10, Dec = 21.10 (J2000 degrees, equivalent to J2000 5h 24m, +21d 6'),
with a statistical uncertainty of 16.96 degrees.

The angle from the Fermi LAT boresight is 78 degrees.
