That is not how time and the speed of light work.
From the reference point of people on earth, we Witnessed it in 1054. It went supernovae ~6,500 years before 1054.
Depending on which reference point you are claiming... your first sentence comes close to something that makes sense... but no matter what reference point you take, the supernovae still happened ~6,500 years earlier than 1054 to someone standing on earth.
