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

At 03:44:03 UT on 3 Feb 2020, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 200203A (trigger 602394248.545582 / 200203156).

The on-ground calculated location, using the Fermi GBM trigger data, is RA = 273.7, Dec = 3.2 (J2000 degrees, equivalent to J2000 18h 14m, 3d 12'), with a statistical uncertainty of 24.0 degrees.

The angle from the Fermi LAT boresight is 47.0 degrees.
