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

At 16:01:52 UT on 27 Jul 2019, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 190727A (trigger 585936117.276574 / 190727668).

The on-ground calculated location, using the Fermi GBM trigger data, is RA = 224.5, Dec = 19.4 (J2000 degrees, equivalent to J2000 14h 58m, 19d 23'), with a statistical uncertainty of 1.0 degrees.

The angle from the Fermi LAT boresight is 20.0 degrees.
