We present an atlas of UV (∼2300 Å) images, obtained with the Hubble Space Telescope (HST) Faint Object Camera, of the central 22″ × 22″ of 110 galaxies. The observed galaxies are an unbiased selection constituting about one-half of a complete sample of all large (D > 6′) and nearby (V < 2000 km s-1) galaxies. This is the first extensive UV imaging survey of normal galaxies. The data are useful for studying star formation, low-level nuclear activity, and UV emission by evolved, stellar populations in galaxies. At the HST resolution (∼0″.05), the images display an assortment of morphologies and UV brightnesses. These include bright nuclear point sources, compact young star clusters scattered in the field or arranged in circumnuclear rings, centrally peaked diffuse light distributions, and galaxies with weak or undetected UV emission. We measure the integrated ∼2300 Å flux in each image, classify the UV morphology, and examine trends between these parameters and the optical properties of the galaxies.
