TITLE: GCN CIRCULAR NUMBER: 30724 SUBJECT: GRB 210827A: Fermi GBM Final Real-time Localization DATE: 21/08/27 10:09:47 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 09:59:24 UT on 27 Aug 2021, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 210827A (trigger 651751169.343218 / 210827416). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 138.3, Dec = 60.2 (J2000 degrees, equivalent to J2000 09h 13m, 60d 12'), with a statistical uncertainty of 20.2 degrees. The angle from the Fermi LAT boresight is 60.0 degrees. The skymap can be found here: https://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2021/bn210827416/q...
