Circular_text TITLE: GCN CIRCULAR NUMBER: 28866 SUBJECT: GRB 201108A: Fermi GBM Final Real-time Localization DATE: 20/11/08 15:38:43 GMT FROM: Fermi GBM Team at MSFC/Fermi-GBM The Fermi GBM team reports the detection of a likely SHORT GRB At 15:28:23 UT on 8 Nov 2020, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 201108A (trigger 626542108.26729 / 201108645). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 289.0, Dec = 35.9 (J2000 degrees, equivalent to J2000 19h 15m, 35d 53'), with a statistical uncertainty of 9.7 degrees. The angle from the Fermi LAT boresight is 66.0 degrees.
