  "body": "The Fermi GBM team reports the detection of a likely SHORT GRB\n\nAt 02:15:08 UT on 22 May 2026, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 260522A (trigger 801108913.782424 / 260522094).\n\nThe on-ground calculated location, using the Fermi GBM trigger data, is RA = 343.6, Dec = 14.1 (J2000 degrees, equivalent to J2000 22h 54m, 14d 05'), with a statistical uncertainty of 5.1 degrees.\n\nThe angle from the Fermi LAT boresight is 10.0 degrees.\n\nThe skymap can be found here:\nhttps://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2026/bn260522094/quicklook/glg_skymap_all_bn260522094.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/bn260522094/quicklook/glg_healpix_all_bn260522094.fit\n\nThe GBM light curve can be found here:\nhttps://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2026/bn260522094/quicklook/glg_lc_medres34_bn260522094.gif\n",
