//////////////////////////////////////////////////////////////////////// TITLE: GCN CIRCULAR NUMBER: 28591 SUBJECT: GRB 201008B: Fermi GBM Final Localization DATE: 20/10/09 15:06:19 GMT FROM: Joshua Wood at MSFC/Fermi-GBM The Fermi GBM team reports the detection of a likely LONG GRB At 18:06:00.94 UT on 8 Oct 2020, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 201008B (trigger 623873165 / 201008754). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 90.8, Dec = 39.3 (J2000 degrees, equivalent to J2000 6h 3m, +39d 18'), with a statistical uncertainty of 4.0 degrees. The angle from the Fermi LAT boresight is 62.1 degrees.
