I swear I saw a supernova once.

It was shortly after my son was born so I was up at odd hours, I also smoked back then so I was outside at 3am taking a smoke break in between feedings.

I was looking up at the stars to the north and saw one get alot brighter for a couple of seconds then it just disappeared.

Could have been some other explanation, but I like to tell myself I witnessed a star dying.
