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

"At 12:57:23.76 UT on 01 January 2024, the Fermi Gamma-ray Burst Monitor (GBM)
triggered and located GRB 240101C (trigger 725806648/240101540).

The on-ground calculated location, using the Fermi GBM trigger data,
is RA = 4.73, Dec = 30.46 (J2000 degrees, equivalent to J2000 0h 18m, +30d 27'),
with a statistical uncertainty of 3.33 degrees.

The angle from the Fermi LAT boresight is 69 degrees.
