88961 Valpertile           Discovered 2001 Oct. 14 by the Asiago-DLR Asteroid Survey at Cima Ekar.
Valerio Pertile (1932-2005) was a skilled and dedicated technician and night assistant at the Asiago Schmidt telescope from 1965 to 2000. He took the major fraction of the 16~000 plates acquired with that telescope, a most precious archive of photographic data.
