The AKARI; satellite has made an All-Sky Survey at six bands in the mid- and far-infrared spectral region. One of the primary goals of the AKARI survey is to produce all-sky infrared source catalogues. We report the release of the first version of the AKARI FIS Bright Source Catalogue (β-1) for four of the six wavelengths (65, 90, 140, 160 μm), containing ˜ 63,000 sources. The detection limit of the most sensitive band (90 μm) is ˜1.3 Jy, corresponding approximately to a 10 σ noise level. The photometric accuracy is 30-60%, depending on the band, and the position uncertainty, currently dominated by the FIS data processing, is 4-5 arcsec. The catalogue was prepared for initial scientific validation by the AKARI science team. The revised version will enter the public domain in Autumn 2009. The two other wavelength bands (9 & 18 μm) data are processed separately for the IRC point source catalogues.
