GRB 230812B: Fermi GBM Final Real-time Localization
Abstract
At 18:58:12 UT on 12 Aug 2023, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 230812B (trigger 713559497.049606 / 230812790). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 250.1, Dec = 46.2 (J2000 degrees, equivalent to J2000 16h 40m, 46d 12'), with a statistical uncertainty of 1.0 degrees. The angle from the Fermi LAT boresight is 29.0 degrees.
