THE UPPSALA-ESO SURVEY OF ASTEROIDS AND COMETS
During 1992 and 1993 the Schmidt telescopes at ESO and Siding Spring were used for The Uppsala-Eso Survey of Asteroids and Comets (UESAC). More than 15000 positions of moving objects were detected on 74 plates and films obtained at the European Southern Observatory in Chile and the Anglo-Australian Observatory in Australia during Jupiter's oppositions in 1992 and 1993. Two or more positions have been secured for about 3400 asteroids, and orbits have so far been calculated for about 2500 asteroids. The majority of these asteroids are previously undetected. So far (March, 2005) 931 asteroids have been permanently numbered. The original observations are available upon request.
We present apparent magnitudes for all observed asteroids and absolute magnitudes for those asteroids with orbits. We present model-diameters based on a Monte Carlo approach using the albedo distribution found by the IRAS Minor Planet Survey. Model-diameters are also calculated for the asteroids observed in the Palomar-Leiden Survey of Faint Minor Planets (PLS). Statistics of the orbital elements are presented and compared with the results of the PLS and the numbered asteroids (Astron.&Astrophys. 318, 631-638).
