More than 60,000 images of Mercury were taken at ~29 deg elevation during twosunrises, at 820 nm, and through a 1.35 m diameter off-axis aperture on theSOAR telescope. The sharpest resolve 0.2" (140 km) and cover 190-300 deglongitude -- a swath unseen by the Mariner 10 spacecraft -- at complementaryphase angles to previous ground-based optical imagery. Our view is comparableto that of the Moon through weak binoculars. Evident are the large craterMozart shadowed on the terminator, fresh rayed craters, and other albedofeatures keyed to topography and radar reflectivity, including the putativehuge ``Basin S'' on the limb. Classical bright feature Liguria resolves acrossthe northwest boundary of the Caloris basin into a bright splotch centered on asharp, 20 km diameter radar crater, and is the brightest feature within aprominent darker ``cap'' (Hermean feature Solitudo Phoenicis) that covers thenorthern hemisphere between longitudes 140-250 deg. The cap may result fromspace weathering that darkens via a magnetically enhanced flux of the solarwind, or that reddens low latitudes via high solar insolation.
