Total solar eclipse August 21, 2017 on Monday From Oregon to South Carolin United States bright light of the Sun total eclipse the stars
What Is a Total Solar Eclipse? A full solar eclipse, known as totality, is almost as dark as night. Complete Solar Eclipse Has 5 Phases
There are 5 stages in a total solar eclipse
Partial eclipse begins 1st contact The Moon starts becoming visible over the Sun’s disk. The Sun looks as if a bite has been taken from it.
Total eclipse begins 2nd contact The entire disk of the Sun is covered by the Moon. Observers in the path of the Moon’s umbra may be able to see Baily’s beads and the diamond ring effect, just before totality.
Totality and maximum eclipse: The Moon completely covers the disk of the Sun. Only the Sun’s corona is visible. This is the most dramatic stage of a total solar eclipse. At this time, the sky goes dark, temperatures can fall, and birds and animals often go quiet. The midpoint of time of totality is known as the maximum point of the eclipse. Observers in the path of the Moon’s umbra may be able to see Baily’s beads and the diamond ring effect, just after totality ends.

Total eclipse ends (3rd contact): The Moon starts moving away, and the Sun reappears. Protect Your Eyes!
Never look directly at the Sun, eclipsed or otherwise, without proper protective eyewear. The Sun’s UV radiation can burn the retinas in your eyes, and cause permanent damage or even blindness.
To watch a solar eclipse safely, wear protective eclipse glasses or project an image of the eclipsed Sun using a pinhole projector.
Only Safe during Full Eclipse
It is safe to view a fully eclipsed Sun, totality, with the naked eye. It is also safe to observe totality through cameras, telescopes or binoculars without any special filters. However, naked eye observations MUST NOT begin until Baily’s beads have completely disappeared (see below). Also, naked eye observations MUST finish before Baily’s beads reappear at the end of totality. Make sure you know how long totality will last at your location.

Watch the total solar eclipse as it makes its way across America in TIME’s livestream event with Amy Shira Teitel and Marsha Ivins
On Aug. 21 the Earth, sun and moon will blow our minds during a total solar eclipse that will last a little more than an hour and 33 minutes, coast to coast. The celestial bodies will line up to block the sun from view, an event scientists and historians are calling the Great American Eclipse.
Here’s why all the excitement: This total eclipse of the sun is the first since 1776 whose path of totality — the narrow corridor where observers will be in the moon’s shadow as it covers the sun — lies completely within the continental United States and no other country.

Alas, it won’t touch California, but that doesn’t mean residents of the Golden State can’t be part of it.
Partial eclipses happen all the time, but this rare cosmic occurrence will turn the summer day dark, reveal stars in the daytime sky and move the black disk of the moon to where the sun should be.
Along the horizon, twilight will glow in sunset colors and the temperature will drop suddenly. Fans liken a total solar eclipse to a spiritual experience, while other experts describe it in poetic terms.
