24778 Nemsu           Discovered 1993 May 24 by C. S. Shoemaker and D. H. Levy at Palomar.
New Mexico State University has developed one of the most advanced astronomy programs in the United States. During the critical space-development years of the 1960s and 1970s, its planetary patrol program provided a badly needed consistency in imaging the planets.
