TITLE: GCN CIRCULAR NUMBER: 30127 SUBJECT: GRB 210605A: Fermi GBM Final Real-time Localization DATE: 21/06/05 05:19:24 GMT FROM: Fermi GBM Team at MSFC/Fermi-GBM The Fermi GBM team reports the detection of a likely SHORT GRB At 05:08:58 UT on 5 Jun 2021, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 210605A (trigger 644562543.389178 / 210605215). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 21.7, Dec = -41.5 (J2000 degrees, equivalent to J2000 01h 26m, -41d 30'), with a statistical uncertainty of 2.0 degrees. The angle from the Fermi LAT boresight is 128.0 degrees.
