Title: Photometry of Cometary Nucleus Candidates and Primitive Asteroids

Abstract: Damocloids are a small, recently identified group of asteroids with high-inclination, high- eccentricity orbits similar to those of Oort Cloud comets. Our 2001 observations of C/2001 OG108 (LONEOS), originally identified as an asteroid before developing a coma, were the first to combine high-resolution spectra with thermal albedo measurements for a comet before perihelion. If the object were in the asteroid belt or the Trojan clouds, it would most likely have been classified as a D-object. We propose to obtain BVRI photometry of another Damocloid near perihelion, along with two to four D and P-type objects which may serve as analogs. We will determine periods, limits to shape, and taxonomic classes where appropriate for all objects.
