Scientific paper

We report a candidate progenitor detection for the nearby type II SN 2012A in NGC 3239 (CBET #2974, #2975, ATEL #3855, #3857, #3860, #3861). We retrieved pre-explosion images of NGC 3239 from the Gemini archive (PID GN-2006A-DD-2; PI P. Michaud) obtained in May 2006 with the NIRI instrument mounted on the Gemini North telescope. The set of images include dithered 20x30s exposures obtained with the NIRI f/14 camera (1024x1024 ALADDIN array; 0.05"/pixel) and the Kprime filter under excellent conditions.
