Abstract

We present CCD surface photometry of 16 nearby dwarf galaxies, many of which were only recently discovered. Our sample is comprised of both isolated galaxies and galaxies that are members of nearby galaxy groups. The observations were obtained in the Johnson B and V bands (and in some cases in Kron-Cousins I). We derive surface brightness profiles, total magnitudes, and integrated colors. For the 11 galaxies in our sample with distance estimates the absolute B magnitudes lie in the range of . The central surface brightness ranges from 22.5 to 27.0 mag arcsec^-2. Most of the dwarf galaxies show exponential light profiles with or without a central light depression. Integrated radial color gradients, where present, appear to indicate a more centrally concentrated younger population and a more extended older population.
