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