  "body": "The Fermi GBM team reports the detection of a likely LONG GRB\n\n\"At 17:06:07.26 UT on 27 May 2025, the Fermi Gamma-ray Burst Monitor (GBM)\ntriggered and located GRB 250527A (trigger 770058372/250527713).\n\nThe on-ground calculated location, using the Fermi GBM trigger data,\nis RA = 30.5, Dec = 15.0 (J2000 degrees, equivalent to J2000 2h 2m, 15d 2'),\nwith a statistical uncertainty of 9.7 degrees.\n\nThe angle from the Fermi LAT boresight is 58.0 degrees.\n\nThe skymap can be found here:\nhttps://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2025/bn250527713/quicklook/glg_skymap_all_bn250527713.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/bn250527713/quicklook/glg_healpix_all_bn250527713.fit\n\nThe GBM light curve can be found here:\nhttps://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2025/bn250527713/quicklook/glg_lc_medres34_bn250527713.gif\"",
