Asteroids that are only observed for a short time can have calculated orbits which have large uncertainties and may be in danger of being lost. Therefore, it is important to recover and observe these asteroids in order to refine their orbital parameters. While some asteroids have not been seen for years, others, although measured (even many times by the surveys), were never identified.

Adding these to the database of unidentified objects increases the amount of computer time needed for identification exponentially. Securing the orbit of these objects allows the assignment of still unidentified measurements, and assures that the asteroid will never be lost, and it probably will be numbered at the next opposition.

We perform targeted searches of faint objects (magnitude between 19 and 20 and beyond) with large uncertainties and in danger of being lost, using dedicated software by J.C. Pelle allowing a high confidence in the identification of the recovered object.
