The Fermi GBM team reports the detection of a likely LONG GRB
At 07:20:08 UT on 27 Feb 2020, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 200227A (trigger 604480813.702942 / 200227306).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 56.9, Dec = 6.3 (J2000 degrees, equivalent to J2000 03h 47m, 6d 17'), with a statistical uncertainty of 1.0 degrees.
The angle from the Fermi LAT boresight is 19.0 degrees.
