The GRB emission has significant detection in \nMCAL up to an energy of about 80 MeV.\n\nThe time integrated spectrum in the time interval [T0, T0+150.0 s]\ncan be fit in the energy range 500 keV - 80 MeV with a single powerlaw\nwith photon index -2.09 (-0.06, +0.08) (reduced chi2 = 0.94 with 39 \nd.o.f.). The estimated fluence is (2.7 � 0.2)x10-4 erg/cm2 in the same \nenergy range. All reported errors are at the 90% confidence level.\n\nAGILE-GRID shows a definite detection above 100 MeV. Further analysis \nare in progress.\n\nThis message may be cited.\"",
