dc.description.abstractHigh resolution observations of H-alpha 6563-A, forbidden O-III 5007 A, and forbidden N-II 6583-A emission lines in the bipolar planetary nebula NGC 2346 are presented. From the widths of the alpha and forbidden N-II lines, an ion temperature of 10,650 + or - 2950 K and a turbulent velocity 16 + or - 2 km/s are derived. Using the detailed radial velocity mapping done by Walsh (1983), a morphological model for the nebula is presented. It is suggested that the observed relative intensities of the approaching and receding components of emission lines in this nebula may very well be interpreted as due to the particular line-of-sight geometry in which the nebula is oriented.en
