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.
