The shadow, a corridor just 96 to 113 kilometres wide, came ashore in OR and then began travelling diagonally across the heartland to SC, with darkness from the totality lasting only around two to three minutes in any one spot.
The path of totality spans about 70 miles (113 kilometers) and will pass through 14 states.
The next partial solar eclipse, after the one that North America will see on August 21, will occur on February 15, 2018, over parts of South America and Antartica.
This rare alignment, in which only the sun's corona is visible, hasn't been seen across the continental U.S. since 1918, and a record number of people are flocking to states where they can see totality. These total eclipses happen every 12 to 18 months somewhere in the world, often over the open ocean since most of the Earth is covered by water. What is an eclipse?

Today's solar eclipse is a uniquely American phenomenon. See the next 50 years' worth of total eclipse locations here. Once you can see the sun again, it won't be safe to look with your naked eye.
Over the weekend, millions of Americans crowded into the narrow celestial interstate from OR to SC known as the "path of totality", where a total solar eclipse appeared briefly on Monday. The last view of the moon's shadow will be seen in Charleston, South Carolina at 4:10 p.m. ET.
The phases of a partial eclipse are not as exciting as a total eclipse.
Remember that a big part of the fun of an eclipse is how it changes everything around you, and not just the sun.
As for the next eclipse to travel over North America, we will have to wait until 2024! If not, another safe method to view the eclipse would involve making a pinhole camera, using only a shoebox and some aluminum foil.
The light from the Sun can burn the retina, leading to permanent or long-term damage and blind spots in one's center of vision.
