Description
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 WR 88, 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.
