THE COMPLEX KINEMATICAL PROPERTIES OF THE HH OBJECTS ALIGNED WITH THEHL TAURI AND HH-30 OUTFLOWS

In a previous paper we reported the detection of emission regions whic h might correspond to the heads of the HL Tauri and HH 30 jets. We now present preliminary proper motion measurements which appear to confir m these identifications. However, we also find that the possible head of the HH 30 jet has a radial velocity of similar or equal to -80 km s (-1), which is in clear disagreement with the low (similar or equal to + 18 km s(-1)) radial velocity which has been measured for the jet. T his result might imply that the jet not only has a change of direction of 14 in the plane of the sky (which is implied by the proper motion measurements), but is also curving towards us by an angle of similar o r equal to 22 degrees.
