TITLE: GCN CIRCULAR NUMBER: 33183 SUBJECT: GRB 230117A: Fermi GBM Final Real-time Localization DATE: 23/01/17 05:14:24 GMT FROM: Fermi GBM Team at MSFC/Fermi-GBM The Fermi GBM team reports the detection of a likely LONG GRB At 05:04:04 UT on 17 Jan 2023, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 230117A (trigger 695624649.253766 / 230117211). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 13.6, Dec = 38.2 (J2000 degrees, equivalent to J2000 00h 54m, 38d 12'), with a statistical uncertainty of 6.5 degrees. The angle from the Fermi LAT boresight is 73.0 degrees.
