  "body": "The Fermi GBM team reports the detection of a likely LONG GRB\n\n\"At 09:18:33.28 UT on 05 August 2026, the Fermi Gamma-ray Burst Monitor (GBM)\ntriggered and located GRB 260805A (trigger 807614318/260805388).\nThis trigger was initially classified as Distant Particles by the flight software,\nbut is in fact a GRB.\n\nThe on-ground calculated location, using the Fermi GBM trigger data,\nis RA = 252.53, Dec = 34.93 (J2000 degrees, equivalent to J2000 16h 50m, +34d 56'),\nwith a statistical uncertainty of 3.11 degrees.\n\nThe angle from the Fermi LAT boresight is 112 degrees.\n\nThe skymap can be found here:\nhttps://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2026/bn260805388/quicklook/glg_skymap_all_bn260805388.png\n\nThe HEALPix FITS file, including the estimated localization systematic, can be found here:\nhttps://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2026/bn260805388/quicklook/glg_healpix_all_bn260805388.fit\n\nThe GBM light curve can be found here:\nhttps://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2026/bn260805388/quicklook/glg_lc_medres34_bn260805388.gif\"",
