We propose to obtain WFPC2 images of the fifty largest main belt asteroids that have favorable apparitions during cycle 9. The images will be searched for companion bodies, as well as mineralogical variegation on the resolved main bodies. Images in the F439W, F673N, F791W, F953N, and F1042M filters will define the 1 micron Fe^2+ feature and the possible 0.7 micron hydration feature. This will allow interpretation of compositional differences between the primary and secondary bodies, as well as any brightness variations across the disk{s} as being due solely to albedo. Because of the restriction that moving target snapshots be done under gyro control, we expect to miss 1/3 of the targets. We therefore request that each candidate be put in the snapshot pool twice, and so request 100 ``targets'' for these fifty asteroids.
