Scientific paper

The results of three-color photometry of 19 nests of interacting galaxies are reported. The integrated color indices of nests are compared with those of normal galaxies in the two-color diagram. The great majority of the objects are found to be blue, some with large ultraviolet excesses. The color indices of the few red nests are typical of elliptical galaxies, and they evidently consist of E or S0 objects. Some of the low-luminosity blue objects may be irregular or other individual galaxies, but the very luminous majority probably consist of close groups of coalescent or contiguous galaxies whose emission lines show the presence of large amounts of gas.
