But it will look amazing.

> When this supernova explodes it will be closer than any known supernova observed to date, and about 19 times closer than Kepler’s supernova. Assuming it explodes as an average Type II super-nova, the optical luminosity will be approximately -12.4, becoming brighter than the full moon.

Typically 3-5 months I think. It's not like it just turns on and off either, it flares up then slowly fades over time.
