TITLE: GCN CIRCULAR NUMBER: 27502 SUBJECT: GRB 200407A: Fermi GBM Final Real-time Localization DATE: 20/04/07 06:32:19 GMT FROM: Fermi GBM Team at MSFC/Fermi-GBM The Fermi GBM team reports the detection of a likely LONG GRB At 06:22:01 UT on 7 Apr 2020, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 200407A (trigger 607933326.481534 / 200407265). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 276.6, Dec = 5.2 (J2000 degrees, equivalent to J2000 18h 26m, 5d 12'), with a statistical uncertainty of 9.2 degrees. The angle from the Fermi LAT boresight is 79.0 degrees.
