What you need to know about Sunday’s super blood moon

TUCSON – An amazing sky show arrives Sunday.
The full moon on January 20th will be a super blood moon total eclipse. Between 8:34-11:51 PM Tucson time, the moon passes through the Earth’s shadow (called the umbra).
Since some sunlight will pass through the Earth’s atmosphere and reach the moon, the moon will take on a reddish tint & not be fully blocked out.
