Meegan (UAH) report on behalf of the Fermi GBM Team:\n\n\"At 00:44:10.57 UT on 30 May 2020, the Fermi Gamma-Ray Burst Monitor (GBM)\ntriggered and located GRB 200530A (trigger 612492255 / GBM200530031),\nwhich was also detected by the Fermi/LAT (Longo et al. 2020, GCN 27891)\nThe Fermi GBM Final Real-time Localization is consistent with the LAT position.\n\nThe angle from the Fermi LAT boresight at the GBM trigger time is 41 degrees.\n\nThe GBM light curve shows a multi-peaked structure\nwith a duration (T90) of about 23 s (50-300 keV).\nThe time-averaged spectrum from T0-1.5 s to T0+28.2 s is\nbest fit by a power law function with an exponential high-energy cutoff.\nThe power law index is -0.55 +/- 0.02 and the cutoff energy, parameterized\nas Epeak, is 178 +/- 4 keV.\n\nThe event fluence (10-1000 keV) in this time interval is\n(2.27 +/- 0.03)E-05 erg/cm^2. The 1-sec peak photon flux measured\nstarting from T0+10.0 s in the 10-1000 keV band\nis 10.9 +/- 0.3 ph/s/cm^2.\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/\"",
