SN 1006 is, as far as Wikipedia knows, the brightest supernova ever recorded by man. It blew up in the year 6194 BC local startime, and seen in (surprise, surprise) the year 1006 earth time (not in Norway, unfortunately) at an estimated visual magnitude of -7.5, about 10 times as bright as venus. According to some sources it was bright enough to cast shadows.
pibbur who can't wait for Betelgeuse to blow up. Or even better, that it blew up some time between 1374 and 1394 AD. Close to 10 million years old, this red supergiant is likely to go nova some time in less than million years. It's companion in the Orion constellation (not exactly, they're more than 200 light years apart), Rigel is also close to termination.
