Circular_text TITLE: GCN CIRCULAR NUMBER: 29646 SUBJECT: GRB 210312A: Fermi GBM Final Real-time Localization DATE: 21/03/12 04:14:35 GMT FROM: Fermi GBM Team at MSFC/Fermi-GBM The Fermi GBM team reports the detection of a likely LONG GRB At 04:04:04 UT on 12 Mar 2021, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 210312A (trigger 637214649.894644 / 210312169). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 68.2, Dec = -16.3 (J2000 degrees, equivalent to J2000 04h 32m, -16d 18'), with a statistical uncertainty of 9.9 degrees. The angle from the Fermi LAT boresight is 47.0 degrees.
