Williams (UCSC),\nreport on behalf of the Fermi LAT Collaboration.\n\nA follow-up analysis of the short bright Fermi GRB 090510 (Ohno et al.,\nGCN 9334, Guiriec et al., GCN 9336) has been performed by the Fermi-LAT\nteam.\n\nFermi LAT has detected more than 50 events above 100 MeV (>10 above 1\nGeV) during the first second and more than 150 events above 100 MeV (>20\nabove 1 GeV) in the first minute after the GBM trigger.\nAll these events are positionally consistent (within the 95% containment\nradius of the LAT point spread function) with the position reported by\nSwift (Goad et al. GCN 9339). They indicate extended emission above GeV\nenergies, making this burst an absolute priority for follow-up searches,\nespecially a redshift determination.\n\nThe points of contact for this burst is:\nMasanori Ohno ohno@astro.isas.jaxa.jp\n\nThe Fermi LAT is a pair conversion telescope designed to\ncover the energy band from 20 MeV to greater than 300 GeV.\nIt is the product of an international collaboration between NASA and DOE\nin the U.S. and many scientific institutions across France, Italy, Japan \nand Sweden.",
