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

At 21:21:49 UT on 1 Sep 2019, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 190901A (trigger 589065714.612092 / 190901890).

The on-ground calculated location, using the Fermi GBM trigger data, is RA = 220.3, Dec = 0.9 (J2000 degrees, equivalent to J2000 14h 41m, 0d 54'), with a statistical uncertainty of 1.0 degrees.

The angle from the Fermi LAT boresight is 85.0 degrees.
