[vsnet-grb-info 41563] GRB 260120A: Fermi GBM Final Real-time Localization
TITLE: GCN CIRCULAR NUMBER: 43467 SUBJECT: GRB 260120A: Fermi GBM Final Real-time Localization DATE: 26/01/20 04:12:25 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 04:01:54 UT on 20 Jan 2026, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 260120A (trigger 790574519.95612 / 260120168). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 345.9, Dec = -24.7 (J2000 degrees, equivalent to J2000 23h 03m, -24d 41'), with a statistical uncertainty of 2.5 degrees. The angle from the Fermi LAT boresight is 72.0 degrees. The skymap can be found here: https://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2026/bn260120168/q...
