13615 Manulis           Discovered 1994 Nov. 28 by C. S. Shoemaker and D. H. Levy at Palomar.
Ilan Manulis (b. 1949) has enthusiastically promoted the study of near-earth objects from Israel and built awareness among the public by lectures and media programs. During the 1980s, he was chairman of the Israeli Astronomical Association. He now serves as IAA's head of small solar-system objects.
