Scientific paper

We propose to make the first X-ray proper motion measurement of SN 1006, by taking an identical 70ks ACIS-S exposure of the bright NE rim to one taken 7 years ago. If X-ray expansion is comparable to radio, then the shock proper motion of 3000 km/s produces a shift of 7 ACIS pixels compared with the reference observation. Proper motion of thin (10 arcsec) nonthermal filaments and interior ejecta knots will be easily detected, as will brightness changes at the 10 percent level on 3-5 arcsec scales. Brightness changes in the nonthermal rims would arise from the influence of spatial variations in magnetic field strength on synchrotron loss timescales. SN 1006 is the best remnant in which to measure the proper motion of nonthermal shocks because it is nearby, bright, and has fast shocks.
