Scientific paper

There still remains some debate about the exact origin of the very blue optical and ultraviolet continuum in Herbig-Haro objects. The authors believe that there is reasonably good evidence for a two-photon continuum in HH-2H. It has recently been suggested that there is a significant contribution to the UV continuumn from scattered light in the general Orion region. The authors present evidence from spatially resolved IUE spectra which indicate the continuum and emission line fluxes have the same spatial distribution. A very low ultraviolet extinction is indicated based upon an enhanced two-photon origin for the UV continuum. A recent observation of HH-24A shows an interesting absence of high excitation emission lines and a weak continuum.
