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

At 09:58:44 UT on 24 Feb 2020, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 200224A (trigger 604231129.56693 / 200224416).

The on-ground calculated location, using the Fermi GBM trigger data, is RA = 270.5, Dec = -56.8 (J2000 degrees, equivalent to J2000 18h 02m, -56d 47'), with a statistical uncertainty of 6.0 degrees.

The angle from the Fermi LAT boresight is 151.0 degrees.
