TITLE: GCN CIRCULAR NUMBER: 28933 SUBJECT: GRB 201120B: Fermi GBM Final Localization DATE: 20/11/20 22:21:08 GMT FROM: Joshua Wood at MSFC/Fermi-GBM The Fermi GBM team reports the detection of a likely LONG GRB At 10:35:49.07 UT on 20 Nov 2020, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 201120A (trigger 627561354 / 201120442). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 78.2, Dec = -57.7 (J2000 degrees, equivalent to J2000 5h 13m, -57d 42'), with a statistical uncertainty of 15.2 degrees. The angle from the Fermi LAT boresight is 26.0 degrees.
