Abstract We propose to obtain WFC H-alpha images of selected supernova remnants to study the physics and proper motions of so-called "collisionless" shocks. The primary targets include portions of the young galactic remnants SN 1006, SN 1572 (Tycho's remnant), and the northeast Balmer-dominated filaments in the Cygnus Loop. We will use the superior imaging quality of HST to resolve the shock structure and provide direct information about the physical scale lengths of the shock fronts. The images will also be crucial for determining accurate proper motions of the filaments (first by comparison with our existing ground-based images, and ultimately with future HST images). These data will help refine the distances and expansion laws of these remnants, information that is critical both for studies of remnant evolution and for the possible use of the historical observations to calibrate Type Ia supernovae as extragalactic distance indicators. Two LMC supernova remnants showing the same Balmer-dominated emission morphology will also be observed as first epoch proper motion images in order to constrain the ages of these remnants and provide an independent distance measurement to the LMC. ------------------------------------------------------------------------------------ 8.
