The GBM on-ground location\nis consistent with the IPN position.\n\nThe angle from the Fermi LAT boresight at the GBM trigger time is 61 degrees.\n\nThe GBM light curve shows multiple overlapping peaks with a duration\n(T90) of about 24 s (50-300 keV). The time-averaged spectrum from T0s\nto T0+29.1 s is best fit by a power law function with an exponential\nhigh-energy cutoff.  The power law index is -0.67 +/- 0.03 and the\ncutoff energy, parameterized as Epeak, is 663 +/- 42 keV.\n\nThe event fluence (10-1000 keV) in this time interval is (2.36 +/-\n0.04)E-5 erg/cm^2. The 1-sec peak photon flux measured starting from\nT0+8.3 s in the 10-1000 keV band is 7.2 +/- 0.2 ph/s/cm^2.\n\nA Band function fits the spectrum equally well with Epeak= 632 +/- 48\nkeV, alpha = -0.66 +/- 0.04 and beta = -2.65 +/- 0.38.\n\nThe spectral analysis results presented above are preliminary;\nfinal results will be published in the GBM GRB Catalog.\"\n\n[GCN OPS NOTE(07jun18):  Per author's request, the \"150605A\" in the \nSubject line was changed to \"180605A\".]",
