  "body": "The Fermi GBM team reports the detection of a likely SHORT GRB\n\n\"At 11:49:10.84 UT on 15 August 2025, the Fermi Gamma-ray Burst Monitor (GBM)\ntriggered and located GRB 250815A (trigger 776951355/250815492). The duration\nand the spectrum suggest an SGR flare, but it is not near the galactic\nplane, so further follow-up is encouraged.\n\nThe on-ground calculated location, using the Fermi GBM trigger data,\nis RA = 221.57, Dec = -1.10 (J2000 degrees, equivalent to J2000 14h 46m, -1d 6'),\nwith a statistical uncertainty of 7.79 degrees.\n\nThe angle from the Fermi LAT boresight is 30 degrees.\n\nThe skymap can be found here:\nhttps://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2025/bn250815492/quicklook/glg_skymap_all_bn250815492.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/2025/bn250815492/quicklook/glg_healpix_all_bn250815492.fit\n\nThe GBM light curve can be found here:\nhttps://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2025/bn250815492/quicklook/glg_lc_medres34_bn250815492.gif\"",
