GRB030320 is the 5th Gamma-ray burst (GRB) detected by INTEGRAL in the fieldof view (FoV). It is so far the GRB with the largest off-axis angle withrespect to the INTEGRAL pointing direction, near to the edge of the FoV of bothmain instruments, IBIS and SPI. Nevertheless, it was possible to determine itsposition and to extract spectra and fluxes. The GRB nature of the event wasconfirmed by an IPN triangulation. It is a ~ 60 s long GRB with two prominentpeaks separated by ~ 35 s. The spectral shape of the GRB is best represented bya single power law with a photon index Gamma ~ 1.7. The peak flux in the 20 -200 keV band is determined to ~ 5.7 photons cm-2 s-1 and the GRB fluence to 1.1x 10-5 erg cm-2. Analysing the spectral evolution of the GRB, a``hard-to-soft'' behaviour emerges. A search for an optical counterpart hasbeen carried out, but none was found.Comment: 5 pages, 3 figures.
