The BEST Guide To The “Total Solar Eclipse” That We’ve Found!

Here is the best website we have found for finding the exact date and time of the solar eclipse in your location: August 21, 2017 — Great American Eclipse (Total Solar Eclipse) which is run by dateandtime.com. It’s easy fast and convenient! Plus there is lots of information on why they occur, what to expect and when the next one will occur! 

Here are 9 things to know about the Solar Eclipse from dateandtime.com.

1. 1st Total Solar Eclipse in 38 Years…

…for those in contiguous United States (excluding Alaska and Hawaii). The last time anyone in mainland US saw a total eclipse of the Sun was on February 26, 1979. If you live in the US and miss this event, you’ll have to wait 7 more years, until April 8, 2024, to see a total solar eclipse from a location in the contiguous United States.

2. Most North Americans Will Be Able To See Totality…

…if they are willing to drive that is. The total eclipse will only be visible along the Moon’s central shadow, which at its widest will be about 115 kilometers (71.5 miles), according to some sources. Its path will span from the country’s West Coast to the East Coast. The rest of North America, as well as Central America and northern parts of South America, will experience a partial solar eclipse. NASA has estimated that a majority of the American population lives less than a 2-day drive away from the path of totality.

3. A Once-In-A-Lifetime Event

While total solar eclipses are not rare—they occur twice every 3 years on average and can be seen from some part of the Earth—a total eclipse of the Sun that can be seen from the American West Coast to the American East Coast occurs less frequently. In fact, the last time a total solar eclipse was visible from coast to coast was almost 100 years ago, on June 8, 1918!

What makes this eclipse extra special is that it is the first time since the total solar eclipse of January 11, 1880 that a total solar eclipse will occur exclusively over the continental United States—no other country will see totality, though many countries will see a partial eclipse of the Sun.

Because of these reasons, the eclipse is also being called the Great American Eclipse.

4. Parts of 14 American States Will Go Dark…

…for the 2 minutes of totality. The Yaquina Head Lighthouse in Newport, Oregon will be the first location on continental US soil to see totality. The partial phase of the eclipse will begin here at 9:04 am local time. Lincoln City, Oregon will also be one of the first locations in the country to experience totality.

Oregonians will also be the first to see totality as the Moon’s shadow moves east at an average speed of about 3600 km/h (2237 mph). After Oregon, the eclipse will move through Idaho, Wyoming, Nebraska, Kansas, Missouri, Illinois, Kentucky, Tennessee, North Carolina, Georgia, and South Carolina. Montana and Iowa are the only states where the path of totality will pass through unpopulated areas. People in Charleston, South Carolina will be some of the last people in the US to see totality.

Nashville, Tennessee is one of the few large cities in the United States to fall completely within the eclipse’s path of totality. Interestingly, only some parts of Kansas City, Kansas and Kansas City, Missouri will be able to see a total solar eclipse.

5. Totality Will Be Spectacular

If you are lucky enough to be in the path of totality, you are in for an astronomical treat, weather permitting, of course. When the eclipse begins, at 1st contact, it will appear as if the Moon is taking a bite out of the Sun. As the eclipse progresses, the sky will get darker, the temperature will drop, and if you pay attention, animals and birds will become quieter.

At 2nd contact, which is when totality begins, Baily’s Beads become visible. As the Moon completely covers the Sun’s surface, the diamond ring can be seen. You might also see pink spots called prominences near the diamond. These spots are caused by gases on the Sun’s surface.

Totality is the only time when one can see the corona, the Sun’s atmosphere. At 3rd contact, Baily’s Beads will once again become visible and a second diamond ring may appear.

6. Stars During the Daytime

As the sky turns dark, planets and stars hidden in the sky by the Sun’s bright light will reappear. Look for Mars, Mercury, Jupiter, and Venus during totality.

7. You Will Need Eye Protection

Do not look directly at the Sun, before, during or after the eclipse without any protective eyewear.

Looking at the Sun with your naked eyes is highly dangerous and can even cause blindness. The safest way to see a solar eclipse is to wear protective eclipse glasses or use a pinhole projector you can easily make yourself.

8. Part of Saros Series 145

Solar eclipses occur in cycles. The Saros cycle, one of the most studied eclipse cycles, occurs every 18 years. Two solar eclipses separated by a Saros cycle have similar features—they occur at the same lunar node, with the Moon roughly at the same distance from the Earth. The eclipses also take place at about the same time of the year and around the same time of day. Eclipses that are separated by a Saros cycle are part of a Saros series.

The August 21, 2017 total solar eclipse belongs to Saros series 145. It is the 22nd eclipse in a series of 77 eclipses. The series began with a partial solar eclipse visible from the Northern Hemisphere on January 4, 1639 and will end with a partial solar eclipse visible from the Southern Hemisphere on April 17, 3009.

The next eclipse in the series—a total solar eclipse—will take place on September 2, 2035.

9. Two Weeks Before: Partial Lunar Eclipse

A solar eclipse always takes place about two weeks before or after a lunar eclipse.

Two weeks before the August 21, 2017 total solar eclipse, on August 7/ 8, 2017, a partial lunar eclipse will be visible from parts of South and East Asia, Europe, Africa, and Australia.
