Abstract
The strong radio source 3C 324 is identified with a faint cluster galaxy, with V ≈ 22.6. Our new CCD spectroscopic data yield an emission-line redshift, z_e = 1.2063. The emission spectrum is narrow-line and shows a characteristic low-ionization level. The strong [O II] fine is both spatially and velocity resolved in 3C 324; a speculative hypothesis on its origin in a rotating and possibly captured gas disk or an infalling galaxy is advanced. The detection of a cluster around 3C 324 is discussed.
