//////////////////////////////////////////////////////////////////////// TITLE: GCN CIRCULAR NUMBER: 26082 SUBJECT: GRB 191028A: Fermi GBM Final Real-time Localization DATE: 19/10/28 04:20:19 GMT FROM: Fermi GBM Team at MSFC/Fermi-GBM The Fermi GBM team reports the detection of a likely LONG GRB At 04:10:01 UT on 28 Oct 2019, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 191028A (trigger 593928606.398038 / 191028174). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 319.2, Dec = -11.3 (J2000 degrees, equivalent to J2000 21h 16m, -11d 18'), with a statistical uncertainty of 8.8 degrees. The angle from the Fermi LAT boresight is 89.0 degrees.
