Abstract
Results of UBVR surface photometry of the two late type galaxies NGC 5 23 and NGC 7678 are presented. The observations were made on the 1-m t elescope at Maidanak Observatory (Uzbekistan) using an electronic imag e converter. Regions of star formation in the galaxies are identified and studied. The composition of the stellar population in the star-for ming regions is estimated using (U-B)(0)-(B-V)(0) two-color diagrams. The mechanisms stimulating star formation in NGC 523 and NGC 7678 are discussed.
