TITLE: GCN CIRCULAR NUMBER: 32546 SUBJECT: GRB 220912A: Fermi GBM Final Real-time Localization DATE: 22/09/12 01:00:39 GMT FROM: Fermi GBM Team at MSFC/Fermi-GBM The Fermi GBM team reports the detection of a likely LONG GRB At 00:50:21 UT on 12 Sep 2022, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 220912A (trigger 684636626.526236 / 220912035). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 165.3, Dec = 49.3 (J2000 degrees, equivalent to J2000 11h 01m, 49d 17'), with a statistical uncertainty of 3.6 degrees. The angle from the Fermi LAT boresight is 81.0 degrees.
