Early risers in Fairbanks were treated to a rare celestial event—a super, blue, blood moon, seen alongside the aurora borealis early Wednesday morning, January 31, 2018. It’s a super moon because the full moon is occurring when the moon is closest to its nearest approach to Earth, making the moon appear larger than normal. In this case, the moon will look about 14 percent bigger than normal. It’s a blue moon because it’s the second full moon in a month. The first occurred on January 1, 2018. And it’s a blood moon because a total lunar eclipse occurs at the same time. During a lunar eclipse, Earth’s shadow has a red tint to it, making the moon appear reddish.
