Abstract
Photometry of 265 galaxies in rich cluster Cl 0024 + 1654 (z = 0.39),
based on CCD imaging in three filters, is presented. The luminosity of
this system ranks it among the richest known clusters, and it has a blue
mass-to-light ratio of about 210. The color-magnitude diagram has a
prominent E/S0 sequence. There are essentially no blue cluster members
brighter than r equals about 19.3, and only very red galaxies inhabit
the central 30 arcsec of the cluster. The blue cluster members have
sizes and surface brightnesses similar to spiral galaxies in nearby
clusters.
