The Great American Solar Eclipse - August 21, 2017 (Total Solar Eclipse)



Eclipse Path
9 Facts about the US Total Solar Eclipse of August 21, 2017
The total phase of the Total Solar Eclipse that will happen on August 21, 2017 can be visible spanning a narrow path across the USA from west coast to east coast, with the weather permitting.  The surrounding areas of the mainland of the US and Canada will be a partial solar eclipse.  Here are some facts you need to know about this once-in-a-lifetime event.  This will be a rare and spectacular sight.
1.       1st Total Solar Eclipse in 38 Years—the last total eclipse occurred on February 26, 1979.  If you miss this event, you’ll have to wait 7 more years to see a total solar eclipse on April 8, 2024 from a location in mainland US.
2.       Most North Americans Will Be Able to See Totality—if you’re willing to drive, that is.
3.       A Once-In-A-Lifetime Event—the first since January 11 1880 that a total solar eclipse occurred exclusively over the mainland US where no other country could see totality, albeit they could see partial eclipse of the Sun.
4.       Part of 14 American States Will Go Dark—for 2 minutes of totality.  The Yaquina Head Lighthouse in Newport, OR will see totality moving 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 will pass over unpopulated areas.  Charleston, SC will be the last to see totality.
5.       Totality Will Be Spectacular—if you pay attention, at  first contact it will appear like the moon is taking a bite out of the Sun, and the sky will get darker, the temperature will drop, and the animals and birds will become quieter.  At second contact, when totality begins, Baily’s Beads will be visible when the Moon completely covers the Sun’s surface—a diamond ring will be seen and pink prominences can be viewed near the diamond.  These spots are caused by gases on the Sun’s surface.  Totality will be the only time to view the corona, or the Sun’s atmosphere.  At third contact, the Baily’s Beads will become visible again and a second diamond ring may appear.
6.       Starts During the Daytime—as the sky turns dark, you may be able to see planets and stars that are hidden in the sky by the Sun’s bright light.  Look for Mars, Mercury, Jupiter, and Venus during totality.
7.       You Will Need Eye Protection—it is important not to look directly at the Sun, before, during, or after the eclipse without proper protective eyewear.  Looking at the Sun with the naked eye is highly dangerous and can cause blindness. If you want to be safe while viewing the eclipse, wear protective eclipse glasses or you can make a pinhole projector.
8.       Part of Saros Series 145—solar eclipses occur in cycles.  The Saros cycle, the most studied eclipse cycle, occurs every 18 years.  They occur within the same lunar node, with the Moon at the same distance from the Earth.  They take place at the same time of year and the same time of day.  The August 21, 2017 total solar eclipse is in this 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 Luna 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.
