TITLE: GCN CIRCULAR NUMBER: 33312 SUBJECT: GRB 230210A: Fermi GBM Final Real-time Localization DATE: 23/02/10 06:24:28 GMT FROM: Fermi GBM Team at MSFC/Fermi-GBM The Fermi GBM team reports the detection of a likely LONG GRB At 06:14:06 UT on 10 Feb 2023, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 230210A (trigger 697702451.965266 / 230210260). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 278.0, Dec = 73.0 (J2000 degrees, equivalent to J2000 18h 32m, 73d 00'), with a statistical uncertainty of 8.9 degrees. The angle from the Fermi LAT boresight is 137.0 degrees.
