Incredibly Rare 'Super Blue Blood Moon' Is About to Appear For The First Time in 150 Years

On January 31, around midnight, the full moon will not only be super, it will be a blue moon and a blood moon.
The blue moon comes as it will be the second full moon in a month. That happens every two and a half years, hence the saying "once in a blue moon".
But wait, wait - these two celestial events, the blue moon and the super moon, will also coincide with a total lunar eclipse.
And with Earth in between the Sun and the Moon, sunlight has to pass through the Earth's atmosphere, which scatters the green to violet light more than it scatters the red light. So the Moon appears red - a blood moon.

The US will miss out on the full spectacle as the eclipse will happen too close to the Moon setting.
