C1 1358 + 6245 at Z = 0.32 - an X-ray selected, distant, rich cluster of galaxies

BVRI CCD photometric observations of an extremely rich, X-ray selected cluster of galaxies, Cl 1358+6245, are presented. Spectroscopy of the optically dominant cluster galaxy indicate a redshift of z = 0.32 for the cluster. The photometric catalog contains 322 galaxies measured in at least two colors detected in the CCD field. The cluster luminosity function and color-magnitude diagrams are included. Cl 1358+6245 is extremely rich, contains a compact, concentrated core of galaxies, exhibits the Butcher-Oemler effect with a blue galaxy fraction 0.10 < f b < 0.18, and is X-ray luminous
