//////////////////////////////////////////////////////////////////////// TITLE: GCN CIRCULAR NUMBER: 27959 SUBJECT: GRB 200616A: Fermi GBM Final Real-time Localization DATE: 20/06/16 01:19:37 GMT FROM: Fermi GBM Team at MSFC/Fermi-GBM The Fermi GBM team reports the detection of a likely LONG GRB At 01:09:15 UT on 16 Jun 2020, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 200616A (trigger 613962560.630758 / 200616048). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 116.2, Dec = -72.2 (J2000 degrees, equivalent to J2000 07h 44m, -72d 12'), with a statistical uncertainty of 4.6 degrees. The angle from the Fermi LAT boresight is 17.0 degrees.
