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

At 02:53:31 UT on 4 Nov 2019, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 191104A (trigger 594528816.391038 / 191104120).

The on-ground calculated location, using the Fermi GBM trigger data, is RA = 271.2, Dec = 18.7 (J2000 degrees, equivalent to J2000 18h 04m, 18d 41'), with a statistical uncertainty of 17.5 degrees.

The angle from the Fermi LAT boresight is 63.0 degrees.
