Visual SN2011B in NGC 2655 at mag. 12.9
Most recent image taken of SN2011B taken from this link (you can see other images and see that the SN is brightening right now).
For those who may not be aware, there is a supernova that came in at mag. 12.9 and is around mag. 13.0 in NGC 2655. Discovered by Koichi Itagaki and Masaki Tsuboi, it is a Type Ia Supernova, which means it is an explosion of a white dwarf star that reached the Chandrasekhar limit of about 1.38 by accretion of mass from its companion star, and then exceeding the electron degeneracy causing the collapse of the white dwarf into carbon fusion. Just a few seconds after the ignition of carbon fusion a runaway reaction occurs, burning into heavier elements and causing the Type Ia Supernova. Here is a link from Bright Supernova on this object, SN2011B.

I will post a finder chart for SN2011B in a couple of hours. NGC 2655 is a 11.0 mag. galaxy above Messier 81 & 82. If you have some time, and want to take a look or try, go for it. Below is an artist rendition of a Type Ia Supernova.
