  "body": "The Fermi GBM team reports the detection of a likely SHORT GRB\n\nAt 13:57:44 UT on 13 Oct 2026, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 261013A (trigger 813592669.12119 / 261013582).\n\nThe on-ground calculated location, using the Fermi GBM trigger data, is RA = 138.6, Dec = 17.6 (J2000 degrees, equivalent to J2000 09h 14m, 17d 36'), with a statistical uncertainty of 15.4 degrees.\n\nThe angle from the Fermi LAT boresight is 97.0 degrees.\n\nThe skymap can be found here:\nhttps://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2026/bn261013582/quicklook/glg_skymap_all_bn261013582.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/bn261013582/quicklook/glg_healpix_all_bn261013582.fit\n\nThe GBM light curve can be found here:\nhttps://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2026/bn261013582/quicklook/glg_lc_medres34_bn261013582.gif\n"
