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

At 06:20:46 UT on 30 Aug 2019, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 190830B (trigger 588838851.35002 / 190830264).

The on-ground calculated location, using the Fermi GBM trigger data, is RA = 159.2, Dec = -54.7 (J2000 degrees, equivalent to J2000 10h 36m, -54d 42'), with a statistical uncertainty of 9.8 degrees.

The angle from the Fermi LAT boresight is 118.0 degrees.
