Circular_text TITLE: GCN CIRCULAR NUMBER: 34106 SUBJECT: GRB 230628C: Fermi GBM Final Real-time Localization DATE: 23/06/28 17:47:08 GMT FROM: Fermi GBM Team at MSFC/Fermi-GBM The Fermi GBM team reports the detection of a likely LONG GRB At 17:36:34 UT on 28 Jun 2023, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 230628C (trigger 709666599.86266 / 230628734). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 301.0, Dec = 35.6 (J2000 degrees, equivalent to J2000 20h 03m, 35d 36'), with a statistical uncertainty of 3.3 degrees. The angle from the Fermi LAT boresight is 18.0 degrees.
