Near-IR magnitudes have been obtained for 136 galaxies in the Coma/A1367 supercluster region, and near-IR colors (J-H) and (H-K) for 90 and 87 objects, respectively. The near-IR colors are contained in a small range and do not depend on morphological types, galaxy inclination, or environment. Optical-to-IR colors depend strongly on a galaxy's morphological type and inclination. There is a dependence of the relative excess of radio, and to a lesser degree, of far-IR emission on recent star formation activity. The magnitude-line width relation for galaxies in Coma and A1367 obtained with these data has a larger spread than previously found with smaller samples. The data suggest a distance modulus to Coma of about 35, regardless of the choice of primary calibrators. 43 refs.
