Although not noted as a supernova, the nebula "Cassiopeia A" was first observed by John Flamsteed on August 16, 1680. It is likely that intervening dust clouds obscured the brightness of the supernova, which might otherwise have been observed in 1667.
Current estimates place the distance from Earth as around 11,000 light years. If that is correct, then the supernova explosion actually took place around 9,000 BCE. (see related link)
