High-velocity knot position versus observing date in the DG Tau blueshifted jet updated from Fig. 5 of Pyo et al. (2003). Solid lines show the proper motions derived by Pyo et al. (2003) for knots A1 and A3. For knots with only one epoch, dashed lines show the typical proper motion range of 027 yr^-1–034 yr^-1. The two new knots observed with SINFONI and knot A2 observed with HST indicate that a new knot typically emerges every 2.5 years since 1991. References for knot positions may be found in Table 1 of Pyo et al. (2003).
