GRB 230803A: Fermi GBM Final Real-time Localization
Abstract
At 01:27:08 UT on 3 Aug 2023, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 230803A (trigger 712718833.154354 / 230803061). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 158.4, Dec = -64.4 (J2000 degrees, equivalent to J2000 10h 33m, -64d 24'), with a statistical uncertainty of 3.3 degrees. The angle from the Fermi LAT boresight is 66.0 degrees.
