On August 21, parts of the United States will be treated to a total solar eclipse — when the moon crosses between the Earth and the sun, and blocks out the sun’s light. The full effect will be visible from a 70-mile-wide band of the country, stretching from Oregon to South Carolina.
Everyone else in the US will see some degree of a partial eclipse, weather permitting.
Business Insider made an interactive map that shows when the solar eclipse will take place in 15 cities across the US.
As the eclipse crosses the country, we will update this post throughout the day with photos showing what it looked like.
