The error circle is slightly asymmetric,\nthe Test Statistic localisation map (with 68% and 90% contours)\ncan be found here: http://fermigrb.stanford.edu/140810782.jpg.\nThe location could be updated later as more data become available\n(at the moment of writing we can analyse up to 2000 s after the trigger).\nThe burst was 123 deg from the LAT boresight at the time of\nthe trigger and the high fluence detected by GBM caused the\nGBM flight software to initiate a Fermi autonomous re-point\nthat placed the source in the LAT FoV about 330 s after the trigger.\n\nThe data from the Fermi-LAT show a significant increase\nin the event rate that is spatially correlated\nwith the GBM emission with high significance.\nMore than 20 photons above 100 MeV and 3 photons\nabove 1 GeV are observed.\nThe highest-energy photon is a 16  GeV event,\nwhich is observed about 1500 s after the GBM trigger.\n\nA Swift ToO has been requested for this burst, but the burst can not\nbe observed due to Sun constrains.\n\nThe Fermi-LAT point of contact for this burst\nis Elena Moretti (moretti@mpp.mpg.de)\n\n\nThe Fermi-LAT is a pair conversion telescope designed\nto cover the energy band from 20 MeV to greater than 300 GeV.\nIt is the product of an international collaboration\nbetween NASA and DOE in the U.S. and many scientific\ninstitutions across France, Italy, Japan and Sweden.",
