15460 Manca           Discovered 1998 Dec. 25 by A. Boattini and L. Tesi at San Marcello Pistoiese.
Francesco Manca (b. 1966), an amateur astronomer at the Sormano Astronomical Observatory, has made several observations of potentially hazardous asteroids, computing for each of them future and past close encounters with our planet.
