On May 31 2011 a new supernova exploded in the nearby (8 Mpc) spiral galaxy M51. Such a nearby event occurs only once every few years. Following its discovery by the Palomar Transient Factory1, we spectroscopically confirmed this was a type II SN, triggering a world-wide multiwavelength follow-up campaign. Including X-ray and UV observations from Swift, CARMA and eVLA in the radio regime, and multitude of visible light and near-IR ground based telescopes. An unprecedented radio spectrum peaked around 1 mm wavelength has been observed. It is unclear at this stage whether the data can be explained using standard circumstellar material (CSM) interaction models, or whether we are seeing a yet unexplained phenomenon (possibly analogous to the unique, bright, short-lived flare detected from SN 1987A). Here we proposed for Spitzer observations of PTF 11eon. Spaced based IR observations are required in order to establish evidence for thermal emission from circumstellar matter around the SN and provide insight regarding dust formation.
