Proposal Type: General Category: Observation Category: Total Time Requested: Prop osal Title: ABSTRACT:
As a follow-up to our ongoing main-belt asteroid observations to correlate the hydration state of low-albedo main-belt asteroids with their radar properties, We propose to make rotationally resolved observations of asteroid ~ 554Peraga. Our previous work has shown a consistent relationship between higher radar albedo and hydrated ~ surface minerals. Asteroid 554Peraga is the only remaining asteroid whose spectra at different rotation phases shows inconsistent hydration states. The radar observations will help determine the asteroid shape, observing geometry, and any inhomogeneities with rotation.
