TITLE: GCN CIRCULAR NUMBER: 30941 SUBJECT: GRB 211019A: Fermi GBM Final Real-time Localization DATE: 21/10/19 06:09:47 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 05:59:31 UT on 19 Oct 2021, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 211019A (trigger 656315976.19434 / 211019250). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 109.2, Dec = -37.8 (J2000 degrees, equivalent to J2000 07h 16m, -37d 47'), with a statistical uncertainty of 1.0 degrees. The angle from the Fermi LAT boresight is 64.0 degrees. The skymap can be found here: https://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2021/bn211019250/q...
