TITLE: GCN CIRCULAR NUMBER: 26659 SUBJECT: GRB 200107B: Fermi GBM Final Real-time Localization DATE: 20/01/07 19:36:52 GMT FROM: Fermi GBM Team at MSFC/Fermi-GBM The Fermi GBM team reports the detection of a likely LONG GRB At 19:26:22 UT on 7 Jan 2020, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 200107B (trigger 600117987.8063 / 200107810). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 356.9, Dec = -80.1 (J2000 degrees, equivalent to J2000 23h 47m, -80d 05'), with a statistical uncertainty of 8.3 degrees. The angle from the Fermi LAT boresight is 61.0 degrees.
