Abstract

We present new spectroscopic observations of WC9 stars. As predicted by Williams & van der Hucht (2000), O ii lines are weak in the dust-free star WR88, which also shows a high ionization. Spectral variability is detected in WR 106 and WR 121. These findings are briefly discussed in terms of the conditions for dust formation in Wolf-Rayet winds.
