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.
