Title: Echoes of Historical Supernovae in the Milky Way Galaxy

Abstract: We propose to continue our search for the first light echoes (LEs) associated with three historical Galactic supernovae: SN 1006, Kepler's SN, and RCW 86. In previously granted NOAO time, we have obtained images of regions of significant dust concentration near several northern and these southern hemisphere Galactic SNRs. To date we have found the light echoes from two SNe in the northern hemisphere, the Cas A supernova of 1680 and the Tycho supernova of 1572 \citeRest08b. We plan to continue our search for light echoes of the other historic Galactic SNe. The study of scattered-light echoes from these Galactic supernovae provides a host of newly-recognized observational benefits which have only just begun to be exploited including (1) a direct comparison of a supernova's original outburst and its current remnant, (2) a three-dimensional view of a supernova, (3) and absolute geometric distances.
