Their X-ray emission processes have become the source of much debate, with implications for both jet physics and cluster feedback models. 3C111 has an extraordinary 2-arcminute long jet that is seen in X-ray, near-IR and radio. At least 8 knots, plus both approaching and receding hotspots and lobes, are seen in the Chandra image. We request additional Chandra, HST and NuSTAR observations, to follow up on possible evidence of variability in two knots, pin down the knots' X-ray spectrum and SED, detect the jet above 10 keV, and study the morphology and X-ray spectrum of the extended lobes. These observations will place the tightest constraints yet on the physics of this fascinating system. We will obtain images of 3C 111, its jet, hotspots, and lobes with WFC3/IR (F110W, F140W, and F160W). This will allow us to characterize all jet components as well as the hotspots in the near-IR, obtain morphological information, and also optical and broadband spectral energy distributions. The latter will allow the fitting of synchrotron emission models. These observations are to occur within 30 days of the approved Chandra observations (this program was approved in the Chandra review). The northern jet pointing (Visit 01) is restricted to an orientation range of 70 degrees in order to include both the AGN core and the hotspot, while avoiding diffraction spikes overlapping the jet. A -90 degree rotation from this would fit everything in the field of view, however there would be a danger of the "Death Star" overlapping the hotspot region, and so we have not included that orientation range. Other rotations of 90 degrees would exclude either the core or the hotspot.
