Spiral galaxy in Leo with supernova

Supernova SN 2012aw was discovered in Messier 95 on March 16, 2012. The supernova is the very bright star below and slightly to the right of the nucleus of the galaxy, in the dim outermost southern arm. In this image, taken 34 days after the discovery, the supernova is still about magnitude 13, making it a fairly easy target for amateur astronomers with medium-sized telescopes.
