Using the MUSTANG 3.3 mm bolometer array on the GBT we have measured the Sunyaev-Zel'dovich Effect (SZE) in the most x-ray luminous cluster known, RXJ1347-1145 (z=0.45) at a resolution of 10'' (fwhm). This is the highest resolution image of the SZE to date and confirms previous indications of a localized departure from pressure equilibrium in the form of a small, very hot (>20 keV) parcel of gas, presumably resulting from a merger shock. We discuss the measurements, their interpretation, and future work.
