GRB 240222A: Fermi GBM Final Real-time Localization
Abstract
At 08:51:31 UT on 22 Feb 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 240222A (trigger 730284696.466782 / 240222369). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 143.3, Dec = -60.4 (J2000 degrees, equivalent to J2000 09h 33m, -60d 23'), with a statistical uncertainty of 9.1 degrees. The angle from the Fermi LAT boresight is 109.0 degrees.
