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

At 06:28:23 UT on 7 May 2019, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 190507A (trigger 578903308.30089 / 190507270).

The on-ground calculated location, using the Fermi GBM trigger data, is RA = 156.0, Dec = -12.8 (J2000 degrees, equivalent to J2000 10h 23m, 12d -48'), with a statistical uncertainty of 4.8 degrees.

The angle from the Fermi LAT boresight is 72.0 degrees.
