Circular_text TITLE: GCN CIRCULAR NUMBER: 31169 SUBJECT: GRB 211204B: Fermi GBM Final Real-time Localization DATE: 21/12/04 12:00:38 GMT FROM: Fermi GBM Team at MSFC/Fermi-GBM The Fermi GBM team reports the detection of a likely LONG GRB At 11:50:05 UT on 4 Dec 2021, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 211204B (trigger 660311410.858238 / 211204493). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 267.9, Dec = 13.5 (J2000 degrees, equivalent to J2000 17h 51m, 13d 30'), with a statistical uncertainty of 2.9 degrees. The angle from the Fermi LAT boresight is 90.0 degrees.
