The variations of the flux density of the core (red circles), core plus knot i (black squares), weak components (magneta up-triangles), knot i (green diamonds) and knot j (maroon down-triangles) (see parts VI–V of Table 2 in BQS17). During the period 2008.54–2010.89 the core flux density is stable at ~1.6 Jy and the light curve of knot i can be derived, assuming the core flux to be 1.62 Jy at 2009.66. This clearly indicates that knot i was ejected before 2009.66. Taking the rising time of the outburst produced by knot i to be ~0.7 ± 0.3 yr, we can infer that knot i was ejected at ~2009.0 ± 0.3 yr.
