1. Introduction

The Uppsala-ESO Survey of Asteroids and Comets (hereafter UESAC) was undertaken to search for unknown comets in the neighbourhood of Jupiter (Tancredi and Lindgren 1994; Lindgren et al. 1995). UESAC consists of surveys around the time of Jupiter's opposition in both 1992 and 1993. A total of 74 plates and films were obtained at the European Southern Observatory in Chile (ESO) and the Anglo-Australian Observatory in Australia (AAO). The plates and films were scanned manually and more than 15 000 trails of moving objects were detected and measured.

In Sects. 2, 3 and 4 we present the main details concerning the observations, reductions and linkage of moving objects. A more thorough description can be found in Lagerkvist et al. (1995), hereafter L95. Statistics of apparent and absolute magnitudes are presented in Sect. 4. We present model-diameters for the asteroids observed in UESAC and the Palomar-Leiden Survey of Faint Minor Planets, hereafter PLS (van Houten et al. 1970), in Sect. 5 and statistics of orbital elements are presented in Sect. 6.
