NGC 439 Cluster
Aug 2 1/22, 1979
103aO + GG385
NGC 439 is the brightest galaxy of a small cluster of at least 30
members ranging in luminosity over at least 8 mag, containing many dE
dwarf ellipticals. The second-brightest galaxy in the group is NGC 441
(SB0_2_(r)/a very early; panel 95) at 2.5' separation. The redshift of
NGC 439 of v_o = 5650 km/s gives a redshift distance of 113 Mpc (H =
50) for a projected linear separation of NGC 441 from NGC 439 of 82
The morphology of NGC 439 is prototypical E5 with no evidence of
an S0 disk, as in NGC 3115 (panel 50), for example.
