TITLE: GCN CIRCULAR NUMBER: 27831 SUBJECT: GRB 200528A: Fermi GBM Final Real-time Localization DATE: 20/05/28 10:37:56 GMT FROM: Fermi GBM Team at MSFC/Fermi-GBM The Fermi GBM team reports the detection of a likely LONG GRB At 10:27:24 UT on 28 May 2020, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 200528A (trigger 612354449.346938 / 200528436). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 169.2, Dec = 60.2 (J2000 degrees, equivalent to J2000 11h 16m, 60d 12'), with a statistical uncertainty of 1.0 degrees. The angle from the Fermi LAT boresight is 19.0 degrees.
