Meegan (UAH)\nreport on behalf of the Fermi GBM Team:\n\n\n\"At 10:19:08.90 UT on 30 May 2019, the Fermi\nGamma-Ray Burst Monitor (GBM) triggered and located\nGRB 190530A (trigger 580904353 / 190530430, GCN #24676),\nwhich was also detected by AGILE-MCAL (GCN # 24678) and\nFermi-LAT (GCN # 24679).\n\nThe GBM light curve consists of multiple bright peaks\nwith a duration (T90) of about 18.4 s (50-300 keV).\n\nThe time-averaged spectrum from T0 to T0+20 s is\nadequately fit by a Band function with Epeak = 900 +/- 10 keV,\nalpha = -1.00 +/- 0.01, and beta = -3.64 +/- 0.12.\n\nThe event fluence (10-1000 keV) in this time interval\nis (3.72 +/- 0.01)E-04 erg/cm^2.\nThe 1-sec peak photon flux measured starting from T0+16.4 s\nin the 10-1000 keV band is 160.5 +/- 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\nFermi GBM Support Page:\nhttps://fermi.gsfc.nasa.gov/ssc/data/access/gbm/\""
