Watch live: NASA feed of solar eclipse
NASA will be broadcasting live the nation's first coast-to-coast total solar eclipse in nearly a century on Monday, Aug. 21.
The eclipse will be visible just after noon in Salem, Oregon, and it will make its way across the United State to Charleston, South Carolina.
In York County, the eclipse will begin at 1:15 p.m. and hit peak coverage about 2:35 p.m. before ending at approximately 4 p.m., according to the Penn State Department of Astronomy and Astrophysics.
The last time a total solar eclipse was visible coast-to-coast in America was 1918, and the next time won't be until 2024, according to NASA.
NASA officials advise people not to look directly at the eclipse unless they're wearing special-purpose solar filters, such as solar glasses.
