A Super Blue Blood Moon will be visible from certain locations on January 31st.
A once-in-a-lifetime ‘lunar trifecta’ will take place in the early hours and will be visible in the Western States of North America, Alaska, and the Hawaiian islands.
A ‘blue moon’ is when there are two full moons which occur in a single month. A ‘super moon’ is when it is closest to the earth, appearing larger than usual. A ‘blood moon’ is when the earth casts a reddish tint onto the moon during a lunar eclipse.
“For the (continental) U.S., the viewing will be best in the West,” said Gordon Johnston, program executive and lunar blogger at NASA Headquarters in Washington. “Set your alarm early and go out and take a look.”
The Jan. 31 full moon is special for three reasons: it’s the third in a series of “supermoons,” when the Moon is closer to Earth in its orbit — known as perigee — and about 14 percent brighter than usual. It’s also the second full moon of the month, commonly known as a “blue moon.” The super blue moon will pass through Earth’s shadow to give viewers in the right location a total lunar eclipse. While the Moon is in the Earth’s shadow it will take on a reddish tint, known as a “blood moon.” “
