Abstract. We present near-infrared and millimetre observations of the large Bok globule CB 34. Two long parallel
trails of H2 knots are discovered on wide-field images in the 1­0 S(1) 2.12 µm emission line. These parsec scale H2
jets extend to the edge of the dark globule where they disappear without the trace of bow shocks. This suggests
