Evolution of the inner jet component properties. (a) Inner jet component paths in xy-coordinates. 1a, 1a1, and 1a2 (green shades) were identified in Britzen et al. (2019b). 1a3, 1a4, and 1a5 are identified in the 15 GHz data from this paper. The most recent data point (cyan) is from epoch 2022.85 and lies close to the path that seems to also be followed by 1a3 and 1a5. 1a3 starts where 1a5 ends; this position is marked by an open black square. The directions of motion for 1a3 and 1a5 are marked by arrows in magenta and orange, respectively. The radio core is indicated by a black filled circle (not to scale). (b) Evolution of the distance from the core for the features shown above (with linear regression as a solid line). (c) Flux densities of those inner jet components that could be traced across the epochs.
