Zhang (MPE) and A. von Kienlin\n(MPE) report:\n\n\"The bright and long GRB detected by IBAS in the INTEGRAL IBIS/ISGRI data\nat 02:44:48 UT on July 11th 2012 (Gotz et al., GCN 13434 ) was also observed\nby the Spectrometer SPI onboard INTEGRAL, in addition to the detection by\nits anticoincidence shield (SPI-ACS). The event was located in the field\nof view of SPI, which allows spectral analysis of this event.\n\nThe light curve from SPI events starts with a precursor at 02:44:50 UT followed \nby a bright double peaked main emission phase at 02:45:55 UT with a duration \nof about 50 sec. The emission during the main peak is seen up to ~3 MeV. \nWe searched for the faint and soft emission after the main outburst reported by \nE. Bozzo et al. (GCN 13435) and S. Golenetskii et al. (GCN 13446). \nWe find a weak tail in the 20 to 100 keV energy range, lasting for about 800 s \nafter the main emission phase .\n\nThe time-integrated spectrum of the main emission phase is well fitted (in\nthe 20 keV - 3 MeV range) by an exponential cutoff powerlaw model, with\nphoton index = 1.00+/-0.03 and an high energy cutoff at 1200 +/- 200 keV.\nThe fluence during the 50 seconds main emission phase in the 20-1000 keV \nrange is (2.26 +/- 0.04)E-4 erg/cm^2.\n\nThe spectral analysis results presented above are preliminary.\"",
