This paper presents photoelectric UBV multiaperture photometry of 144 galaxies, 139 of which are associated with six nearby bright clusters. The observations were made at the McDonald Observatory from 1986 September to 1987 November and were part of the production of the Third Reference Catalogue of Bright Galaxies (RC3). The observations were used to compute total magnitudes and color indices published in RC3. The observations can also be used to calibrate CCD images. (C) 1996 American Astronomical Society.
