Bissaldi (University & INFN Trieste),\nreport on behalf of the Fermi-LAT team:\n\nAt 19:46:32.2 on February 19, 2014, Fermi LAT detected high-energy emission\nfrom GRB 140219A, which was also detected by Fermi-GBM (trigger 414531995\n- Zhang et al., GCN 15866) and located by IPN (Hurley et al., GCN 15864).\nGRB 140219A was not observable by LAT until ~T0+500 s due to\nEarth occultation and it remained in the LAT field of view from ~T0+500 s\nuntil T0+2300 s.\n\nAn analysis of the LAT data over a period covering ~T0+500 s to ~T0+2300 s\nreveals a marginal detection with a TS of about 25 using the center of\nthe IPN error box.\n\nThe best LAT on-ground location is RA, Dec 158.2, 7.2 (J2000). The 90%\ncontainment region (statistical error only) is asymmetrical with a width of\n2.75 deg\nand a height of 1.65 deg compatible with the IPN contour\n(see http://fermigrb.stanford.edu/GRB140219A_tsmap.jpg).\n\nThe highest energy photon with a probability of being associated with\nthe GRB > 90% is a 1.6 GeV photon at T0+1350 s.\n\nThe Fermi LAT point of contact for this burst is Sylvain Guiriec\n(sylvain.guiriec*@nasa.gov <http://nasa.gov>*).\n\nThe Fermi LAT is a pair conversion telescope designed to cover the energy\nband\nfrom 20 MeV to greater than 300 GeV. It is the product of an international\ncollaboration between NASA and DOE in the U.S. and many scientific\ninstitutions\nacross France, Italy, Japan and Sweden.",
