Bright new Supernova SN2012cg in Galaxy NGC 4424

On May 17th the automated Lick Supernova Search discovered the SN 2012cg supernova in galaxy NGC 4424 in the constellation Virgo. From 18th magnitude it has now brightened to 12.0 and rivals the core of the galaxy for brightness. This exploding star was originally a White Dwarf star equivalent in mass to our own Sun and locked in a binary orbit with a much larger star. It steadily drew matter from this companion star up to a point where it became unstable, collapsed in on itself and exploded, producing what is known as a Type Ia supernova. This spectacular event should be visible in telescopes of 6″ diameter and above.
