High-quality CCD images and long-slit spectra obtained for the bow shock-like Herbig-Haro (HH) object HH 34 and its associated jet were studied in detail. Within 26 arcsec of its source, the jet was found to have at least 12 knots with a characteristic spacing of 1.2-2.5 arcsec. North of the source, a new bow shock-like object (HH 34N) was discovered, which lies in the opposite direction to HH 34, which is now called HH 34S; both HH objects show a clumpy structure. A comparison of the observations of HH 34 N and the HH 34S with current bow shock models revealed a few major discrepancies.
