  "body": "The Fermi GBM team reports the detection of a likely LONG GRB\n\n\"At 05:37:34.86 UT on 08 November 2026, the Fermi Gamma-ray Burst Monitor (GBM)\ntriggered and located GRB 261108B (trigger 815809059/261108234).\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 = 264.86, Dec = 80.18 (J2000 degrees, equivalent to J2000 17h 39m, +80d 10'),\nwith a statistical uncertainty of 1.57 degrees.\n\nThe angle from the Fermi LAT boresight is 62 degrees.\n\nThe skymap can be found here:\nhttps://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2026/bn261108234/quicklook/glg_skymap_all_bn261108234.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/bn261108234/quicklook/glg_healpix_all_bn261108234.fit\n\nThe GBM light curve can be found here:\nhttps://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2026/bn261108234/quicklook/glg_lc_medres34_bn261108234.gif\"",
