A very young Type II Supernova ( PSN J11185695+1303494) has been discovered in the Leo galaxy Messier 65.
Although it is currently below 16th magnitude as the supernova was discovered so early on in its development, it should continue to brighten over the next few weeks.
With the galaxy lying at a distance of around 35 million light years away the supernova should reach a maximum brightness of around 11th magnitude.
This should bring it within easy range of fairly modest amateur telescopes as it brightens.
