  We have measured the proper motion (PM) and kinematics of the ansae in NGC
7009 using high dispersion echelle spectra and archive narrow band HST images.
Assuming that the ansae are moving at equal and opposite velocities from the
central star we obtain a system radial velocity of -53+-2km/s, the eastern ansa
approaching and the western ansa receding at Vr=5.3+-1km/s with respect to this
value. The PM of the eastern ansa is 28+-8mas/yr, which with our weighted
distance to NGC 7009 of 0.86+-0.34kpc gives Vexp=112+-32km/s. The electron
temperature and density in both ansae were determined to be Te=9000+-400K and
Ne=2300+-400/cc. The dynamic age of the ansae is 925+-260yrs.and the implied PM
of the central star is 1+-0.5mas/yr. This is in qualitative but not
quantitative agreement with previous work.
