32897 Curtharris           Discovered 1994 Aug. 1 by C. S. Shoemaker and D. H. Levy at Palomar.
Curtis Harris (b. 1952) has placed the first search telescope for comets and minor planets in the Caribbean region. When complete, his observatory will combine comet research with an extensive program of public outreach for the nation of Anguilla, offering for the first time a window to science in that region.
