W. Li and A. V. Filippenko, University of California, Berkeley, report that they have isolated a possible progenitor for the young type-II supernova in M51 (ATel 3398)in Hubble Space Telescope images of M51 (GO/DD program 10452) taken with the Advanced Camera for Surveys (ACS). A geometrical transformation between a stacked KAIT (Lick Observatory) image of the SN taken on Jun 3.26 UT and the ACS images has yielded the identification of an object in the ACS images that is within the 0".09 uncertainty of the supernova position; this object was detected in the F435W (B), F555W (V), F658N (H-alpha), and F814W (I) band images.
