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

At 07:08:56 UT on 9 Oct 2019, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 191009A (trigger 592297741.769374 / 191009298).

The on-ground calculated location, using the Fermi GBM trigger data, is RA = 26.8, Dec = 65.7 (J2000 degrees, equivalent to J2000 01h 47m, 65d 42'), with a statistical uncertainty of 1.4 degrees.

The angle from the Fermi LAT boresight is 40.0 degrees.
