Connaughton (University of Alabama, Huntsville), J. McEnery (NASA/GSFC) and E.Sonbas (Adiyaman Univ.) report on behalf of the Fermi-LAT team:\n\nAt UT 11:24:47 on June 19, 2014, Fermi-LAT detected high-energy emission from GRB 140619B, which was also detected by Fermi-GBM (trigger 424869883 / 140619475).  A preliminary analysis of GBM data characterizes this event as a short hard burst, with a T90 duration of ~0.5s (GCN 16419).\n\nThe best LAT on-ground location is found to be:\n\n(RA, Dec) = 132.68, -9.66 (deg, J2000)\n\nwith an approximate error radius of 0.06 deg (90% containment, statistical error only).\n\nThis was 32 deg from the LAT boresight at the time of the trigger. The data from the Fermi-LAT show a significant increase in the event rate within ~3 degree of the GBM location after the GBM trigger that is spatially and temporally correlated with the GBM emission with high significance. More than 19 photons above 100 MeV and more than 5 photons above 1 GeV are observed within 5 seconds. The highest-energy photon is a 24 GeV event which is observed 0.61 seconds after the GBM trigger.  \n\nThe Fermi-LAT point of contact for this burst is Eda Sonbas edasonbas@yahoo.com.\n\nA Swift ToO has been requested for this burst.\n\nThe Fermi-LAT is a pair conversion telescope designed to cover the energy band from 20 MeV to greater than 300 GeV. It is the product of an international collaboration between NASA and DOE in the U.S. and many scientific institutions across France, Italy, Japan and Sweden.",
