For the one-dimensional complex Ginzburg-Landau equation (CGLE) we obtain, by a shooting algorithm, a family of uniformly propagating hole solutions which differ from the well-known Nozaki-Bekki holes. These holes occur in many regimes of the CGLE, most prominently in the regime known as spatiotemporal intermittency. A stability analysis reveals that these holes have one unstable core mode, and we discuss the consequence of this for the intermittent states.
