The paper presents new monochromatic images, long-slit echelle spectra, and theoretical position-velocity diagrams of the Herbig-Haro objects HH 46 and HH 47. The outer bow shock HH 47D extends almost all the way back to the infrared source driving the outflow in a narrow-band forbidden II image of the region, but is not easily visible in H-alpha and forbidden S II. The discovery of a counterjet in forbidden S II reported by Reipurth is confirmed.
