The X-ray emission from the remnant of the supernova of 1006 AD is dominated by a lineless continuum, almost certainly synchrotron radiation from 100 TeV electrons on the tail of the nonthermal-electron distribution. Models for the integrated spectrum including thermal and synchrotron components are in good agreement with observations. However, the synchrotron emission is expected to vary strongly with position in the remnant, and spectral variations could contain information on the variation of acceleration with the angle between the shock normal and the ambient magnetic field, and on other remnant properties. We show calculations of the synchrotron X-ray emission expected from various regions of a Sedov-phase supernova remnant encountering a uniform upstream medium, and compare them to spatially resolved observations of SN 1006.
