Opportunity of a Lifetime Experience

On August 21, there will be an opportunity of a lifetime for many people across the United States. They will get to see a total solar eclipse! This will be the first total eclipse of the Sun visible in the continental United States since 1979 and the first to cross the country since 1918.

The total solar eclipse will begin its travel on land on the west coast of Oregon and move at about 1800 miles per hour to the east coast of South Carolina. Because the Moon moves across the sky from east to west, the shadow will move from west to east crossing the country in about an hour and a half. It will be total for only a little more than two minutes at any location on the path of totality. The path will be about 70 miles wide through the center of the country.

A total eclipse is much different from a partial eclipse. On a clear day with a 90 percent eclipse coverage, the Sun would still be brighter than on most cloudy days. Even a 99 percent eclipse does not have the same impact as a total eclipse. When the Moon completely blocks the Sun, it will be like nighttime. When this eclipse is at totality, Jupiter, Mercury, Mars, and Venus will be visible along with bright stars.

The most impressive sight will be one that you can only see during a total eclipse—the Sun’s corona. The corona contains particles of matter ejected from the Sun and traveling thousands of miles out into space. The particles follow the magnetic field of the Sun, and they are constantly changing with that field. The corona is always there, but it’s normally blocked from view by the scattered light in Earth’s atmosphere. Even though the corona is much dimmer than the surface (photosphere) of the Sun, it is many times hotter.

This is also the opportunity of a lifetime to see the darkness of night in the middle of the day. Looking around on the ground during totality, animals and insects may begin their nighttime activities. There will only be a 360-degree sunset-like glow on the horizon from refraction of sunlight outside of the full shadow (umbra) of the Moon.

For the moments of totality (in this case a little more than two minutes), you will be able to look directly at the Sun without special solar filters. Except for the brief time of totality DO NOT LOOK DIRECTLY AT THE SUN. Of course, if you are not in the area of the TOTAL eclipse, it is NEVER safe to look at the Sun. Many universities, libraries, and science centers have special glasses available to block the visible and UV light which could permanently damage your eyes. DO NOT USE SUNGLASSES! They will not protect your vision.

There is an interactive app that you can put on your Android or iPhone to monitor the eclipse. Just go to your app store and search for “Eclipse Safari.” NASA will be live-streaming the eclipse from across the country. You can find the live stream through Eclipse Safari or by going to nasa.gov or NASA’s YouTube channel or Facebook page.

We hope you will enjoy this opportunity of a lifetime to observe one of the wonders of God’s creation SAFELY.
