Meegan (UAH)\nreport on behalf of the Fermi GBM Team:\n\n\"At 01:49:35.08 UT on 30 June 2020, the Fermi Gamma-Ray Burst Monitor (GBM)\ntriggered and located GRB 200630A (trigger 615174580 / 200630076)\nwhich was also detected by the Swift/BAT (Page et al. 2020, GCN 28043)\nand the Swift/XRT (Beardmore et al. 2020, GCN 28044).\nThe Fermi GBM Final Position is consistent with the Swift position.\n\nThe angle from the Fermi LAT boresight at the GBM trigger time is 42\ndegrees.\n\nThe GBM light curve shows one main peak\nwith a duration (T90) of about 7 s (50-300 keV).\nThe time-averaged spectrum from T0-1.5 s to T0+3.56 s is\nbest fit by a single power law function with index of -1.51 +/- 0.05.\n\nThe event fluence (10-1000 keV) in this time interval is\n(1.41 +/- 0.12)E-06 erg/cm^2. The 1-sec peak photon flux measured\nstarting from T0-0.19 s in the 10-1000 keV band\nis 2.9 +/- 0.2 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\nPage:\nhttps://fermi.gsfc.nasa.gov/ssc/data/access/gbm/\"",
