TITLE: GCN CIRCULAR NUMBER: 36663 SUBJECT: GRB 240612B: Fermi GBM Final Real-time Localization DATE: 24/06/12 12:26:59 GMT FROM: Fermi GBM Team at MSFC/Fermi-GBM do_not_reply@GIOC.nsstc.nasa.gov
The Fermi GBM team reports the detection of a likely LONG GRB
At 12:16:17 UT on 12 Jun 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 240612B (trigger 739887382.859234 / 240612511).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 328.8, Dec = 11.5 (J2000 degrees, equivalent to J2000 21h 55m, 11d 30'), with a statistical uncertainty of 5.8 degrees.
The angle from the Fermi LAT boresight is 68.0 degrees.
