Abstract
In this paper we describe the results of the first optical kinematic study of the planetary nebula BD+30 degrees 3639, This system has a central star of the Wolf-Rayet type and is believed to be fairly young. Emission-line sp ectra were obtained at high spectral and spatial resolution using the Utrec ht echelle spectrometer at the William Herschel Telescope. These spectra in dicate that the main ionized shell of BD + 30 degrees 3639 appears to be ev olving in a more complex way than previously thought.
