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

At 06:41:50 UT on 1 Oct 2019, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 191001A (trigger 591604915.579128 / 191001279).

The on-ground calculated location, using the Fermi GBM trigger data, is RA = 308.9, Dec = 18.5 (J2000 degrees, equivalent to J2000 20h 35m, 18d 30'), with a statistical uncertainty of 3.3 degrees.

The angle from the Fermi LAT boresight is 102.0 degrees.
