Where will you be on August 21? Hopefully near a window.

You wouldn't want to miss out on a solar eclipse!

The astronomical event happens when the moon passes in between the sun and the Earth, blocking the sun for a little over an hour.

The solar eclipse will be viewable for cities that fall in the horizontal path of totality from 9:06 a.m. in Oregon all the way to 4:06 p.m. Eastern time in South Carolina on August 21.

The eclipse will only be viewable for about an hour and a half in each city. Cities outside of the totality path will see a partial eclipse.
