The unusual 'X-shaped' large-scale radio morphology of this source is thought to be the result of a recent merger-induced reorientation, and the jet displays a remarkable series of 'cannonball' ejections clearly detected in radio through X-rays. The clarity of the optical features and nearness of the source make it an ideal target for a prospective HST proper-motions study. Previous HST proper-motion studies which revealed superluminal motions in M87 and 3C 264 relied on archival WFPC2 observations and long observing baselines. With the high astrometric precision possible with an all-ACS/WFC imaging study, we can reach 0.5c accuracy with a time baseline of 4 years, requiring only a single additional orbit in cycles 24 and 26, in combination with our existing ACS/WFC imaging from 2015. We also request complimentary near-UV observations (WFC3/UVIS F225W) in order to map the spectral evolution of the knots and hotspot and allow better constraints on the emission mechanisms and physical parameters in the jet. This is an imaging project for the optical jet located in nearby elliptical galaxy 4C +00.58. The ACS/WFC F606W observations are identical in setup to the previous imaging done in cycles 22 and 24. The imaging in all three epochs (22,24,26) in the F606W filter are part of a proper-motions monitoring project. In addition, two orbits of WFC3/UVIS imaging in F225W were taken in cycle 24, in order to measure the synchrotron spectrum of the resolved knots in the jet. For the ACS/WFC imaging, we use a 5-point dithering pattern which covers the chip gap, optimized to sample the PSF. ORIENT constraints are included as a caution against possible saturation spikes from the bright quasar core over-running the jet. While the core was not saturated in previous imaging with similar exposure times, quasar cores are known to be variable.
