//////////////////////////////////////////////////////////////////////// TITLE: GCN CIRCULAR NUMBER: 26255 SUBJECT: GRB 191117B: Fermi GBM Final Real-time Localization DATE: 19/11/17 15:28:00 GMT FROM: Fermi GBM Team at MSFC/Fermi-GBM The Fermi GBM team reports the detection of a likely LONG GRB At 15:17:38 UT on 17 Nov 2019, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 191117B (trigger 595696663.360798 / 191117637). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 156.1, Dec = 11.7 (J2000 degrees, equivalent to J2000 10h 24m, 11d 41'), with a statistical uncertainty of 7.4 degrees. The angle from the Fermi LAT boresight is 54.0 degrees.
