The remnant of SN 1006 AD shows both thermal and nonthermal X-ray emission. Thermal emission shows strong lines of O and a clumpy morphology, while the nonthermal (synchrotron) emission is concentrated in narrow arcs at the remnant edge. We present images of SN 1006 in various lines, and localized spectral analysis, based on Chandra observations from Cycles 1 and 2. While these observations do not cover the entire remnant, they include emission at a large range of radii and azimuthal position. We use elemental abundance analysis to attempt to locate the reverse shock and to separate ejecta emission from emission from shocked interstellar material. We also characterize the synchrotron component as a function of position, with implications for the maximum energy to which electrons are accelerated and the mechanism limiting that energy.
