Abstract [en]

We obtained an unfiltered image of the Type IIP SN 2012aw (CBET 3054) from the Nordic Optical Telescope + ALFOSC on 2012 March 19.9 UT, under excellent (~0.5") seeing conditions. 6 sources were identified in both the the ALFOSC image, and a pre-explosion HST+WFPC2 F555W mosaic of M95 retrieved (together with F439W and F814W-filter images) from the Hubble Legacy Archive. Using a geometric transformation derived from the position of the fiducial sources in both images, SN 2012aw was located in the WFPC2 image to an accuracy of 0.24". We find SN 2012aw to be coincident with a faint, red source in the pre-explosion WFPC data, which is the probable progenitor.
