The Fermi GBM team reports the detection of a likely SHORT GRB
At 14:50:52 UT on 18 Jul 2020, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 200718A (trigger 616776657.413512 / 200718619).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 295.1, Dec = -3.9 (J2000 degrees, equivalent to J2000 19h 40m, -3d 53'), with a statistical uncertainty of 16.3 degrees.
The angle from the Fermi LAT boresight is 76.0 degrees.
