  "body": "The Fermi GBM team reports the detection of a likely SHORT GRB\n\nAt 11:00:12 UT on 1 Jun 2026, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 260601A (trigger 802004417.438878 / 260601458).\n\nThe on-ground calculated location, using the Fermi GBM trigger data, is RA = 15.1, Dec = 44.4 (J2000 degrees, equivalent to J2000 01h 00m, 44d 23'), with a statistical uncertainty of 2.0 degrees.\n\nThe angle from the Fermi LAT boresight is 30.0 degrees.\n\nThe skymap can be found here:\nhttps://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2026/bn260601458/quicklook/glg_skymap_all_bn260601458.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/bn260601458/quicklook/glg_healpix_all_bn260601458.fit\n\nThe GBM light curve can be found here:\nhttps://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2026/bn260601458/quicklook/glg_lc_medres34_bn260601458.gif\n",
