While the eclipse will already be happening by the time the moon rises for some residents of Alaska and Hawaii, people in the rest of the country will have a chance to see every stage of the event, depending on local weather conditions.

The final stages will begin shortly after that with the whole astronomical event wrapping up shortly before 1 a.m. Monday morning.
Total lunar eclipses on average come about once a year; however, from Sunday night, January 20, through Monday morning, January 21, both the North and South American continents will get the see the sun, Earth, and moon line up perfectly to show the entirety of the eclipse for the first time in almost two decades.
While solar eclipses are risky to view directly, the light from lunar eclipses is much fainter and so is completely safe to view without special equipment.
If the skies are clear, the entire eclipse will also be visible in North and South America, as well as Greenland, Iceland, Ireland, Norway, Sweden, Portugal and the French and Spanish coasts.

This eclipse has been referred to as a "supermoon".
