TITLE: GCN CIRCULAR NUMBER: 29416 SUBJECT: GRB 210207A: Fermi GBM Final Real-time Localization DATE: 21/02/07 14:38:23 GMT FROM: Fermi GBM Team at MSFC/Fermi-GBM The Fermi GBM team reports the detection of a likely LONG GRB At 14:27:58 UT on 7 Feb 2021, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 210207A (trigger 634400883.983828 / 210207603). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 138.0, Dec = 4.7 (J2000 degrees, equivalent to J2000 09h 11m, 4d 42'), with a statistical uncertainty of 6.0 degrees. The angle from the Fermi LAT boresight is 89.0 degrees.
