Come on Eta Carinae -- Explode Already!

The death watch is on for Eta Carinae, a relatively nearby massive
star that's set to explode as a supernova. The Chandra X-Ray
Observatory delivered this beautiful photograph of the star and its
surrounding nebula; layers of material that it's already shed in its
death throes.
When it does explode, Eta Carinae is going to be spectacular. It's
thought to have between 100 and 150 times the mass of our own Sun.
Not only that, it's a mere 7,500 light years away. Its brilliant
display of fireworks will rival the light of the full Moon, and
should be easy to see in the middle of the day; you could read a book
by it at night.
Will it count as 'light pollution' when it goes?
