Abstract
ABSTRACT Spectroscopic observations of NGC 3314 are presented. Long-slit spectrograms clearly show two sets of emission lines stemming from the two superposed galaxies. The foreground galaxy, NGC 3314a, is a type SBbc or SBc spiral of absolute magnitude MB ≈ -20 and has a radial velocity czsun; = 2835±15 km s-1. The background galaxy, NGC 3314b, is probably an Sb of MB ≈ -20.5 with czsun; = 4641±6 km s-1. The availabe evidence suggests that at least NGC 3314a, and probably also NGC 3314b, are members of the Hydra I cluster of galaxies (czsun; = 3699 km s-1, σv = 681 km s-1), although the alternative hypothesis that one of them or both are field galaxies cannot presently be ruled out.
