  "body": "The Fermi GBM team reports the detection of a likely LONG GRB\n\nAt 09:18:12.01 UT on 17 February 2026, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 260217A (trigger 793012697/260217388).\n\nThe on-ground calculated location, using the Fermi GBM trigger data,\nis RA = 278.43, Dec = -5.30 (J2000 degrees, equivalent to J2000 18h 34m, -5d 18'),\nwith a statistical uncertainty of 11.59 degrees.\n\nThe angle from the Fermi LAT boresight is 91 degrees.\n\nThe skymap can be found here:\nhttps://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2026/bn260217388/quicklook/glg_skymap_all_bn260217388.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/bn260217388/quicklook/glg_healpix_all_bn260217388.fit\n\nThe GBM light curve can be found here:\nhttps://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2026/bn260217388/quicklook/glg_lc_medres34_bn260217388.gif",
