A single-orbit visit with the WFC3/UVIS would allow, in combination with the previous ACS/WFC images obtained in 2003-2005, an astrometric precision of less than 0.05 mas, almost one order of magnitude better than our previous result. Precise knowledge of the kinematics of all of the stars in the region is crucial for determining which one might be the surviving binary companion of the supernova. A precise reconstruction of the parameters of the binary system that gave rise to the supernova would then be possible, complementing the existing observations both from the ground and with the HST, which span the last fourteen years. ------------------------------------------------------------------------------------ Observations Description ------------------------ This proposal collect images for a subsequent epoch of the field previously observed by ACS/WFC in 2003-2005. We maximized the number of images, and have large dither pattern for internal check of the geometric distortion solution. Parallel observations of ACS/WFC proved to be useless, and weak the primary science. We will not collect parallel ACS/WFC observations.
