Preparing for the August 2017 Total Solar Eclipse | NASAhttps://www.nasa.gov/feature/goddard/2016/preparing-for-the-august-2017-total-solar-eclipseOn Aug. 21, 2017, the moon will pass in front of the sun and cast a shadow upon all of North America, coast-to-coast, for the first time since 1918. The total solar eclipse begins near Lincoln City, Oregon, at 10:15 a.m. PDT (1:15 p.m. EDT). Totality ends at 2:48 p.m. EDT near Charleston, South Carolina. The partial eclipse will start earlier and end later, but the total eclipse itself will take about one hour and 40 minutes to cross the country. For areas within the narrow path of “totality” (100% eclipse), the air will cool as complete darkness falls in the middle of the day for up to 2 minutes and 40 seconds.
