TITLE: GCN CIRCULAR NUMBER: 9584 SUBJECT: Fermi LAT observations of GRB 090626 DATE: 09/06/28 19:08:13 GMT FROM: Valerie Connaughton at MSFC Fred Piron (LPTA), Francesco Longo (INFN/Trieste), Giulia Iafrate (INAF/OA Trieste), Teddy Cheung (NASA/GSFC), Hiro Tajima (SLAC) and Valerie Connaughton (UAH) report on behalf of the Fermi LAT collaboration: Ground processing of data from the Fermi Large Area Telescope (LAT) reveals that the LAT significantly detects emission from GRB 090626, reported as a bright Fermi Gamma-ray Burst Monitor (GBM) burst (von Kienlin GCN 9579). The LAT localization of this burst is RA, Dec = 170.01, -33.50 ± 0.32 deg (statistical, 95% CL), with an additional systematic error estimated at 0.1 deg. There appears to be significant emission above 100 MeV until about 250 s after the GBM trigger time. Further information will be available following more detailed analysis. The point of contact for this burst is Fred Piron (frederic.piron@lpta.in2p3.fr). The 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. This message can be cited.
