2017 Solar Eclipse
Prepare for the solar eclipse of Monday, August 21, 2017.
All of North America will see a partial solar eclipse, and a narrow swath from Oregon to South Carolina will experience a total solar eclipse. This will likely be the most observed celestial event in US history. Make your plans now.
