GRB 230911A: Fermi GBM Final Real-time Localization
Abstract
At 03:09:32 UT on 11 Sep 2023, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 230911A (trigger 716094577.87568 / 230911132). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 59.8, Dec = -34.4 (J2000 degrees, equivalent to J2000 03h 59m, -34d 23'), with a statistical uncertainty of 4.1 degrees. The angle from the Fermi LAT boresight is 50.0 degrees.
