Omodei (Stanford), and \nE.Bissaldi (Politecnico & INFN Bari) report on behalf of the Fermi-LAT Collaboration:\n\nAt 10:19:08 UT on 2019-05-30, Fermi-LAT triggered on high-energy emission from long GRB 190530A, \nwhich was also detected by Fermi-GBM (GCN 24676) and AGILE-MCAL (GCN 24678).\n\nThe best LAT on-ground location is found to be:\nRA, Dec = 120.76, 35.5 (J2000) \nwith an error radius of 0.12 deg (90% containment, statistical error only).\n\nThis was 63 deg from the LAT boresight at the time of the trigger and 3.5 deg from the center of the GBM \nlocalization (GCN 24676).\n\nThe data from the Fermi-LAT show a significant increase in the event rate that is temporally correlated with \nthe GBM emission with high significance.\n\nThe highest-energy photon is a 8.7 GeV event which is observed 96 seconds after the GBM trigger.\nThe photon flux above 100 MeV in the time interval 0-200s after the GBM trigger is 2.9 e-04 ph/cm2/s \n+/- 2.9 e-05.\n\nThe estimated photon index above 100 MeV is -2.7 +/- 0.1.\n\nThe Fermi-LAT point of contact for this burst is Francesco Longo (francesco.longo@ts.infn.it).\n\nThe Fermi-LAT is a pair conversion telescope designed to cover the energy band from 20 MeV to greater \nthan 300 GeV.  It is the product of an international collaboration between NASA and DOE in the U.S. and \nmany scientific institutions across France, Italy, Japan and Sweden.",
