//////////////////////////////////////////////////////////////////////// TITLE: GCN CIRCULAR NUMBER: 26932 SUBJECT: GRB 200129A: Fermi GBM Final Real-time Localization DATE: 20/01/29 09:59:05 GMT FROM: Fermi GBM Team at MSFC/Fermi-GBM The Fermi GBM team reports the detection of a likely SHORT GRB At 09:48:44 UT on 29 Jan 2020, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 200129A (trigger 601984129.18217 / 200129409). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 346.3, Dec = -45.0 (J2000 degrees, equivalent to J2000 23h 05m, -45d 00'), with a statistical uncertainty of 13.1 degrees. The angle from the Fermi LAT boresight is 111.0 degrees.
