TITLE: GCN CIRCULAR NUMBER: 25692 SUBJECT: GRB 190910A: Fermi GBM Final Real-time Localization DATE: 19/09/10 00:49:51 GMT FROM: Fermi GBM Team at MSFC/Fermi-GBM The Fermi GBM team reports the detection of a likely LONG GRB At 00:39:37 UT on 10 Sep 2019, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 190910A (trigger 589768782.860244 / 190910028). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 229.5, Dec = 9.1 (J2000 degrees, equivalent to J2000 15h 18m, 9d 05'), with a statistical uncertainty of 6.6 degrees. The angle from the Fermi LAT boresight is 61.0 degrees.
