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

At 23:04:55 UT on 20 Jan 2020, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 200120A (trigger 601254300.33796 / 200120962).

The on-ground calculated location, using the Fermi GBM trigger data, is RA = 139.4, Dec = -70.7 (J2000 degrees, equivalent to J2000 09h 17m, -70d 42'), with a statistical uncertainty of 1.0 degrees.

The angle from the Fermi LAT boresight is 148.0 degrees.
