Malacaria (NASA-MSFC/USRA) reports on behalf of the Fermi GBM Team:\n\n\"At 09:44:59.37 UT on 02 April 2018, the Fermi Gamma-Ray Burst\nMonitor triggered and located GRB 180402A\n(trigger 544355104 / 180402406).\n\nThe event was also detected by the Swift/BAT\n(Lien et al. 2018, GCN 22580).\nThe GBM on-ground location is consistent with the Swift position.\n\nThe LAT boresight angle is 90 degrees.\n\nThe duration (T90) is 0.448 +/- 0.326 s (8-1000 keV).\nThe time-averaged spectrum from T0-0.1 s to T0+0.2 s is best fit\nby a Band function.\nThe best-fit parameters are: Alpha = 2.23 +/- 2.03,\nBeta = -1.35 +/- 0.04, Epeak = 123.80 +/- 44.00 keV.\n\nThe event fluence (8-1000 keV) in this time interval is\n(8.69 +/- 0.62)E-07 erg/cm^2.\nThe 1-sec peak photon flux measured starting from T0+0 s in the\n10-1000 keV band is 17.5 +/- 1.4 ph/s/cm^2.\n\nThe spectral analysis results presented above are preliminary;\nfinal results will be published in the GBM GRB Catalog.\"",
