Filter photographs with the UK 1.2-m Schmidt Telescope have revealed bright ionized knots in the cores of the galactic H II regions M16 and the Rosette nebula. Both low- and very high-dispersion spectra of these have now shown that several have high-speed components which are bright in the emission lines from lowly ionized species. In the Rosette nebula it is proposed that they could be Herbig-Haro-like objects driven by newly formed stars embedded in the approaching side of an expanding shell. Alternatively, they could be bow shocks around globules overrun by this shell and exposed to the powerful wind from the central OB association or collimated flows in the channels between adjacent globules but still driven by the central wind.
