Blood moon viewing in Sacramento unhampered by any clouds

Clear skies provided Northern California residents prime viewing of a so-called blood moon during a total lunar eclipse overnight.

The second in a series of four blood moons appeared during the early morning hours.

The total moon eclipse in Sacramento began around 3:45 a.m. Wednesday.

In a total lunar eclipse, the entire moon is shadowed by earth, according to NASA. The face of the moon turns sunset red or coppery - hence the blood moon name -- for an hour or more as the eclipse unfolds.

Two full lunar eclipses will also happen next year.
