Abstract

We present observations obtained with the Goddard High Resolution Spectrograph (GHRS) of three O-type stars:ξ per (O7 III),λ Cep (O6 Iaf) and 10 Lac (O9 V). These observations show evidence of instabilities in the winds of all three stars, although not necessarily those expected from current models of structured winds.
