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.
[2] The observations were taken at ESO's La Silla Observatory site in Chile, with a total of 74 obtained photographic plates, and at the Anglo-Australian Observatory (Siding Spring Observatory) in Australia.
More minor planets may yet to be numbered and added to this list as their orbits are confirmed.
