M- and E-class main-belt asteroid radar observations

We continue our long term goal of observing M- and E-class main belt asteroids (MBAs) with the S-band radar system. In this cycle, we propose to observe the last ma jor E-class MBA not yet observed, 64 Angelina, and our 21st M-class asteroid, 69 Hesperia. Our previous observations of E-class asteroids show them to have the highest radar polarization ratio of any asteroid, suggesting an unusual surface texture, composition, or combination of these. Our observations of M-asteroids show that approximately one-third have radar albedos consistent with metallic surfaces and to have significant variations in radar albedo with rotation, a feature not seen in most other MBAs. Our continuing survey of these ob jects will help us determine their composition and nature.
