North and Central America and a tiny sliver of South America will have the best view. Weather permitting, skygazers in those regions should be able to view the entire eclipse, expected to last 3 1/2 hours.
The moon is normally illuminated by the sun. During a total lunar eclipse, the full moon passes through the shadow created by the Earth blocking the sun's light.
Total eclipse begins at 11:41 p.m. PST Monday or 2:41 a.m. EST Tuesday. The totality phase - when the moon is entirely inside Earth's shadow - will last a little over an hour.
