GRB 210411D: Fermi GBM Final Real-time Localization
Abstract
At 16:31:10 UT on 11 Apr 2021, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 210411D (trigger 639851475.876502 / 210411688). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 358.5, Dec = 24.3 (J2000 degrees, equivalent to J2000 23h 53m, 24d 18'), with a statistical uncertainty of 3.6 degrees. The angle from the Fermi LAT boresight is 55.0 degrees.
