  On January 6th 2004, the IBAS burst alert system triggered the 8th gamma-ray
burst (GRB) to be detected by the INTEGRAL satellite. The position was
determined and publicly distributed within 12s, enabling ESA's XMM-Newton to
take advantage of a ToO observation just 5 hours later during which the x-ray
afterglow was detected. Observations at optical wavelengths also revealed the
existence of a fading optical source. The GRB is ~52s long with 2 distinct
peaks separated by ~24s. At gamma-ray energies the burst was the weakest
detected by INTEGRAL up to that time with a flux in the 20-200 keV band of 0.57
photons/cm^2/s. Nevertheless, it was possible to determine its position and
extract spectra and fluxes. Here we present light curves and the results of
imaging, spectral and temporal analyses of the prompt emission and the onset of
the afterglow from INTEGRAL data.
