We propose to obtain to obtain UVBI imaging for spiral and irregular galaxies (mostly dwarf galaxies)within a distance of 11 Mpc. Ten nights are requested on the CTIO 0.9m telescope to observe 31 galaxies in the Southern Hemisphere. The requested data combined with H(alpha), R and UV imaging from our 11HUGS GALEX Legacy project will provide a comprehensive multi-wavelength image atlas of the local universe. The UBV colors will be used to constrain the star formation history. For example, this data will allow us to shed light on the correlation between underlying galaxy color and current star formation activity. In addition, the deep I-band imaging will trace the structure of the underlying (older) stellar disk, which is necessary to test whether the star formation properties are tied in any way to the stellar mass distribution. The surface photometry will also allow to study the photometric properties, the morphology, and spatial distribution of the different stellar populations.
