TITLE: GCN CIRCULAR NUMBER: 31052 SUBJECT: GRB 211107A: Fermi GBM Final Real-time Localization DATE: 21/11/07 20:31:01 GMT FROM: Fermi GBM Team at MSFC/Fermi-GBM <do_not_reply@GIOC.nsstc.nasa.gov> The Fermi GBM team reports the detection of a likely LONG GRB At 20:20:40 UT on 7 Nov 2021, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 211107A (trigger 658009245.216482 / 211107848). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 183.4, Dec = -61.2 (J2000 degrees, equivalent to J2000 12h 13m, -61d 12'), with a statistical uncertainty of 17.9 degrees. The angle from the Fermi LAT boresight is 87.0 degrees. The skymap can be found here: https://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2021/bn211107848/q...
