Bissaldi (Politecnico and INFN Bari)\nreports on behalf of the Fermi GBM Team:\n  \n\n\"At 07:56:33.25 UT on 14 July 2021, the Fermi Gamma-Ray Burst Monitor (GBM)\ntriggered and located GRB 210714A (trigger 647942198 / 210714331),\nwhich was also detected by Konus-Wind (Frederiks et al. 2021, GCN 30467).\n\nThe on-ground calculated location, using the GBM trigger data, is\nRA = 313.67, DEC = -51.59\n(J2000 degrees, equivalent to 20 h 54 m, -51 d 35'),\nwith a statistical uncertainty\nof 1 degree (radius, 1-sigma containment,\nstatistical only; there is additionally a systematic\nerror which we have characterized as a core-plus-tail model, with 90% of\nGRBs having a 3.7 deg error and a small tail suffering a larger than 10 deg\nsystematic error. [Connaughton et al. 2015, ApJS, 216, 32]).\n\nThe angle from the Fermi LAT boresight at the GBM trigger time is 109 degrees.\n\nThe GBM light curve consists of a bright, FRED-like pulse\nwith a duration (T90) of about 42 s (50-300 keV).\nThe time-averaged spectrum from T0 to T0+25 s is\nbest fit by a Band function with Epeak = 64 +/- 5 keV,\nalpha = -0.68 +/- 0.09, and beta = -1.75 +/- 0.01.\n\nThe event fluence (10-1000 keV) in this time interval is\n(4.67 +/- 0.15)E-05 erg/cm^2. The 1-sec peak photon flux measured\nstarting from T0+1.9 s in the 10-1000 keV band\nis 48.9 +/- 0.7 ph/s/cm^2.\n  \n\nThe spectral analysis results presented above are preliminary;\nfinal results will be published in the GBM GRB Catalog:\nhttps://heasarc.gsfc.nasa.gov/W3Browse/fermi/fermigbrst.html\n\nFor Fermi GBM data and info, please visit the official Fermi GBM Support Page:\nhttps://fermi.gsfc.nasa.gov/ssc/data/access/gbm/\"",
