GRB 221215B: Fermi GBM Final Real-time Localization
Abstract
At 16:09:34 UT on 15 Dec 2022, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 221215B (trigger 692813379.070912 / 221215673). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 23.2, Dec = 32.0 (J2000 degrees, equivalent to J2000 01h 32m, 32d 00'), with a statistical uncertainty of 4.1 degrees. The angle from the Fermi LAT boresight is 35.0 degrees.
