The supernova resulted from a exploding red supergiant and lies just 21 million light years away. It's the closest core-collapse supernova to us since SN 1993J which lit up M81 (some 12 million ly away) in Spring 1993. The SN is designated of type II-L (L for 'linear') , which is characterised by a rapid rise to maximum brightness followed by a slow and gradual decrease, that is thought to be brought about by ejection of the dead stars' outer hydrogen shell.
