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. 2001); 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.

Abstract. The DENIS programme (Deep European Near-Infrared southern sky Survey) is carrying out a groundbased survey of the southern sky with the aim of providing 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. With respect to the exposure time of the observations, asteroids are included in the point source catalog as any other regular point-like object. Up to now, we have identified 1233 asteroids, numbered between 1 and 8000, on the basis of their predicted positions following a recognition procedure described here. Their I, J, K magnitudes are being compiled in electronic tables available at the CDS via anonymous ftp 130.79.128.5.

The Deep European Near-Infrared southern sky Survey (DENIS) has been observing the sky since december of 1995, in the three bands I, J, K of the near-infrared, in order to provide to the community a deep and extensive photometric catalogue of stars and galaxies. In addition, the asteroids will be included in the catalogue as any other regular point sources. Therefore, in the frame of asteroidal taxonomies, this project appeared as a good opportunity to enlarge the asteroid colorimetry data base to new colours and more objects. In order to use the DENIS data for our case, we had, as a first step, to determine all the asteroids observed during the survey to recover them in the catalogue of magnitudes. We present here our recovery procedure and our final expectations. The ultimate aim of this study will be to improve our knowledge on the compositional structure of the asteroidal population.
