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

At 05:39:33 UT on 1 Feb 2023, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 230201A (trigger 696922778.405158 / 230201236).

The on-ground calculated location, using the Fermi GBM trigger data, is RA = 346.5, Dec = 43.8 (J2000 degrees, equivalent to J2000 23h 06m, 43d 47'), with a statistical uncertainty of 9.7 degrees.

The angle from the Fermi LAT boresight is 126.0 degrees.
