Rare black moon rises Friday

You've heard the WMC First Alert Weather Team talk about supermoons and blue moons, but there's another type of moon that you may not have seen before.

A black moon is the second new moon in a single month, which differs from the blue moon that is the second full moon in a month. This black moon will only be for those of us living in the Western Hemisphere, since the eastern hemisphere won't technically experience the full moon until the next day (October 1st). 

Unfortunately, you won't be able to spot the black moon in the sky on Friday. A new moon is when the moon is in Earth's shadow, so it will not be illuminated or visible to the human eye. 

Although you won't be able to see the moon on September 30, you will have a great view of the rest of the sky. Without the glow of the moon, it is much easier to spot stars and constellations in the night sky. It will be mostly clear on Friday, so you're stargazing won't be impacted by cloud cover either. 

A black moon occurs about every two and a half years, so the last one was in 2014.
