The Uppsala-ESO Survey of Asteroids and Comets (UESAC) took place in 1992–1993. A large number of asteroids were investigated. Over 15,000 positions were detected, and orbits were calculated for 2500. As of 2006, a total of 1002 new asteroids were discovered and numbered in the process, ranging from 6102 Visby to (120498) 1993 FD53. More may yet be added as their orbits are confirmed.
