TITLE: GCN CIRCULAR NUMBER: 44733 SUBJECT: GRB 260529A: Fermi GBM Final Real-time Localization DATE: 26/05/29 03:00:37 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 02:49:57 UT on 29 May 2026, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 260529A (trigger 801715802.916756 / 260529118). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 302.8, Dec = -15.3 (J2000 degrees, equivalent to J2000 20h 11m, -15d 18'), with a statistical uncertainty of 4.2 degrees. The angle from the Fermi LAT boresight is 90.0 degrees. The skymap can be found here: https://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2026/bn260529118/q...
