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.

Stephen Lesage (UAH) reports on behalf of the Fermi GBM Team:

"The Fermi Gamma-ray Burst Monitor (GBM) trigger 602394248 / 200203156
at 03:44:03.55 UT on 03 February 2020, tentatively classified as
GRB 200203A (GCN 26969), is most likely not due to a GRB. This trigger
is likely an SGR event.

GBM triggers
602392636 / 200203137 at 03:17:11.95 UT on 03 February 2020
and
602455182 / 200203861 at 20:39:37.97 UT on 03 February 2020
are also likely SGR events."
