This is Earthfiles Linda Moulton Howe reporting from Stanley Idaho August 21, 2017. We are here with around 100 amateur astronomers from The Boise Astronomical Society to witness the 2017 total solar eclipse over the continental U.S. From coast to coast, this eclipse will span over 2,500 miles but will have a width of only 70 miles. Linda Moulton Howe stands at the center of this 70-mile-wide band to view the eclipse’s totality. About 13 minutes before totality, a chill sweeps over the area as the Moon comes close to completely eclipsing the Sun. At 11:28 a.m, totality sweeps over the area, covering the sky with a murky, greenish twilight. The horizon looks eerily incandescent, glowing from the fires blazing in the nearby forests. Stars are briefly visible to the naked eye.
The last total solar eclipse to occur over the mainland U.S was 1,581 years ago and the next one will occur in 2316. This solar eclipse is part of a predictable and recurring set of eclipses, known as a Saros cycle. This particular cycle, Saros 145, began with a partial eclipse in 1639 and will finally conclude in 3009.
