TITLE: GCN CIRCULAR NUMBER: 24732 SUBJECT: GRB 190603A: Fermi GBM Final Real-time Localization DATE: 19/06/03 19:16:10 GMT FROM: Fermi GBM Team at MSFC/Fermi-GBM The Fermi GBM team reports the detection of a likely LONG GRB At 19:04:25 UT on 3 Jun 2019, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 190603A (trigger 581281470.98357 / 190603795). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 20.1, Dec = 40.9 (J2000 degrees, equivalent to J2000 01h 20m, 40d 53'), with a statistical uncertainty of 5.9 degrees. The angle from the Fermi LAT boresight is 57.0 degrees.
