  "body": "The Fermi GBM team reports the detection of a likely LONG GRB\n\nAt 12:01:36 UT on 12 May 2025, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 250512A (trigger 768744101.290912 / 250512501).\n\nThe on-ground calculated location, using the Fermi GBM trigger data, is RA = 318.9, Dec = 76.7 (J2000 degrees, equivalent to J2000 21h 15m, 76d 42'), with a statistical uncertainty of 9.5 degrees.\n\nThe angle from the Fermi LAT boresight is 104.0 degrees.\n\nThe skymap can be found here:\nhttps://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2025/bn250512501/quicklook/glg_skymap_all_bn250512501.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/bn250512501/quicklook/glg_healpix_all_bn250512501.fit\n\nThe GBM light curve can be found here:\nhttps://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2025/bn250512501/quicklook/glg_lc_medres34_bn250512501.gif\n",
