1. Vesta is the third largest asteroid with a mean diameter of 530 km (P. C. Thomas et al., Icarus, in press). All other known basaltic asteroids are <10 km in diameter.
2. At its closest distance in May 1996, Vesta was 1.17 AU from Earth, within 0.03 AU of its closest possible approach. At that time, its apparent diameter was 0.62 arc sec, or about 15 pixels across as viewed with WFPC2.

5. The 1996 data were obtained through filters F439W (wavelength of 0.439 μm), F673N (0.673 (μm), F791N (0.791 μm), F953N (0.953 μm), and F1042M (1.042 μm) at solar phase angles of about 5°.
6. Our limb-finding program models the position of an illuminated margin; this software was calibrated to 0.05 pixel with WFPC2 images of Ganymede and Europa taken in June and July 1995. For purposes of fitting an overall ellipsoidal shape model, the low phase angles of the Vesta observations allow correction of terminator positions to nominal limb positions: maximum nominal correction is 5 km for the 1994 data (0.1 pixel) and 1 km for the 1996 data (0.03 pixel).

13. The position and diameter of the (10°N, 270°W) feature correspond to a geologic feature interpreted to be present on the basis of rotationally-resolved ground-based spectroscopy performed by M. J. Gaffey [Icarus 127, 130 (1997)].
14. Because this large structure has a central peak, we chose the term "crater" instead of "basin," as the latter most properly refers to multiringed features.

26. Because of the difficulty of uniquely solving for the photometric function out to the limb, as more fully described in (22), we were limited in our geologic investigation to a northern latitude of 56° and a southern latitude of -44°. Thus, we were unable to measure color ratios of the deepest part of the south pole basin or of the central peak.

56. The largest fragment is estimated to be 10 km across. Whether it has the structure of a single coherent fragment or a gravitationally bound group of fragments is unknown, although a conglomerate composition for Vesta fragments is suggested by coincident exposure age peaks for the categories of HED meteorites, as found by O. Eugster and T. Michel (Geochim. Cosmochim. Acta 59, 177 (1995)].
