We find a surface brightness discontinuity in the gas $\\sim$3.5 kpc from the nucleus spanning a 120$^\\circ$ arc. The temperature of the gas is 0.60$\\pm$0.05 and 0.68$\\pm$0.10 keV, interior and exterior to the discontinuity, respectively. The elemental abundance is poorly constrained by the spectral fits, but if the abundance is constant across the discontinuity, there is a factor of 2.3$\\pm$0.4 pressure jump across the discontinuity.
