Abstract
UBV photometry of Ho 124 group galaxies NGC 2805, NGC 2814, NGC 2820, and Mk 108 was carried out. Blue condensations (''stellar aggregates'' ) were singled out in central regions and spirals of these galaxies. T he two-color diagram location of the condensations corresponds to the region occupied by young objects of 10(6) - 10(7) year age according t o models of galactic photometric evolution. The enhanced star formatio n rate in the galaxies of Ho 124 group is probably due to intergalacti c interaction causing distortions of their symmetry.
