Abstract
The Air Force Maui Optical Station (AMOS) has demonstrated follow-up astrometry and photometry for near-earth objects (NEOs), with results published in the Minor Planet Circulars. Although this information is important for the cataloging of all NEOs, it does not provide all of the data needed to assess the potential hazard posed by these objects, i.e. composition, size, shape, and dynamics. AMOS has increased its capability by adding a six position filter wheel (in conjunction with Phillip's Laboratory's Geophysics Directorate and the University of Arizona), for use on the Jet Propulsion Laboratory's CCD camera mounted on the AMOS 1.2 meter telescope. The paper provides the rationale for three-color photometry for determination of NEO characteristics, as well as preliminary results of the observations of several NEOs an main-belt asteroids. It also discusses the design of a photo-polarimeter, to be built in the near future, which will add more capability to AMOS, and determination of albedo and size of NEOs of particular interest to both the scientific and government communities.
