Abstract

The DENIS programme (Deep European Near-Infrared Southern Sky Survey) has carried out a ground-based survey of the southern sky to provide an extensive I, J, K photometric catalog of point and extended sources. The limiting magnitudes of the three bands I, J, K centered at 0.8, 1.25 and 2.15 μm are respectively 18.5, 16.5 and 13.5. Given the short exposure time of the observations, asteroids have been included in the point source catalog as any other regular point-like object. We have searched the first 8000 asteroids on the basis of their predicted positions following a recognition procedure described previously (Baudrand et al. [CITE]); in this first release based on the DENIS data available in January 2001 we recovered 1233 asteroids. We present here the second release which provides 767 asteroids. Their I, J, K magnitudes are compiled in electronic tables available at the CDS.
