Astrometry and Light Curves of Asteroids with the SUBARU Telecope

We present the reductions of observations of a single ecliptic field, carried out over one night in September 2, 2002, at the focus of the SUBARU 8.2 m telescope. The frames necessary for the reduction were retrieved through the database SMOKA (Subaru Mitaka Okayama Kiso Archive System) High frequency multi shots imaging of the fields enable to detect sub-kilometric asteroids and to perform astrometric and photometric reduction, leading in some cases to the extraction of light curves.
