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

At 10:19:08 UT on 30 May 2019, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 190530A (trigger 580904353.903198 / 190530430).

The on-ground calculated location, using the Fermi GBM trigger data, is RA = 116.9, Dec = 34.0 (J2000 degrees, equivalent to J2000 07h 47m, 34d 00'), with a statistical uncertainty of 1.0 degrees.

The angle from the Fermi LAT boresight is 63.0 degrees.
