//////////////////////////////////////////////////////////////////////// TITLE: GCN CIRCULAR NUMBER: 28604 SUBJECT: GRB 201012A: Fermi GBM Final Real-time Localization DATE: 20/10/12 05:46:04 GMT FROM: Fermi GBM Team at MSFC/Fermi-GBM The Fermi GBM team reports the detection of a likely LONG GRB At 05:35:38 UT on 12 Oct 2020, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 201012A (trigger 624173743.502338 / 201012233). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 303.7, Dec = -33.5 (J2000 degrees, equivalent to J2000 20h 14m, -33d 30'), with a statistical uncertainty of 3.4 degrees. The angle from the Fermi LAT boresight is 57.0 degrees.
