GRB 230313A: Fermi GBM Final Real-time Localization
Abstract
At 11:38:43 UT on 13 Mar 2023, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 230313A (trigger 700400328.006796 / 230313485). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 202.4, Dec = 47.2 (J2000 degrees, equivalent to J2000 13h 29m, 47d 12'), with a statistical uncertainty of 1.6 degrees. The angle from the Fermi LAT boresight is 107.0 degrees.
