On Monday, August 21, 2017, all of North America will be treated to an eclipse of the sun. Anyone within the path of totality can see one of nature’s most awe inspiring sights - a total solar eclipse.

This path, where the moon will completely cover the sun and the sun's tenuous atmosphere - the corona - can be seen, will stretch from Salem, Oregon to Charleston, South Carolina.

Observers outside this path will still see a partial solar eclipse where the moon covers part of the sun's disk.

    This celestial event is a solar eclipse in which the moon passes between the sun and Earth and blocks all or part of the sun for up to about three hours, from beginning to end, as viewed from a given location. For this eclipse, the longest period when the moon completely blocks the sun from any given location along the path will be about two minutes and 40 seconds. The last time the contiguous U.S. saw a total eclipse was in 1979.

    You never want to look directly at the sun without appropriate protection except during totality. That could severely hurt your eyes. However, there are many ways to safely view an eclipse of the sun including direct viewing – which requires some type of filtering device and indirect viewing where you project an image of the sun onto a screen. Both methods should produce clear images of the partial phase of an eclipse. Click here for eclipse viewing techniques and safety.

    You can use this interactive map from NASA to zoom in on the path and find out the exact locations from which it will be visible. Remember, even 99.99 % magnitude is not the same as totality.

    This eclipse for someone located in Greenville AL will only achieve about 90% magnitude:

    A nice partial, but honestly, this level of eclipse would not cause anyone to become very excited.

    However, for those in Greenvile KY or Greenville SC, the eclipse will reach this 90% level, and then will continue on toward totality! People there WILL experience totality, and will be amazed.

    So that’s why we say that for Alabama, this eclipse is only going to be so many % partial – yet the 2017 eclipse can still rightfully be called a “total” eclipse. It’s total for some people!

    But you have to be in the path!

    Fake Solar Eclipse Glasses Are Flooding the Market: How to Stay Safe

    The Federal Trade Commission has released a statement with safety guidelines for solar viewing glasses.

    https://www.consumer.ftc.gov/blog/planning-watch-eclipse-read-first?utm_source=govdelivery

    Start by making sure that the glasses or viewers you’re considering have the manufacturer’s name and address printed somewhere on the product, and are certified as safe. The certification means the glasses and solar viewers have met an international safety standard and are safe for your eyes. Only consider products marked with ISO 12312-2, which means that the product has met the international safety standard. According to the American Astronomical Society, to date, only five manufacturers meet the standard for this certification:

    American Paper Optics
    Baader Planetarium (AstroSolar Silver/Gold film only)
    Rainbow Symphony
    Thousand Oaks Optical
    TSE 17

    What else do you need to know to watch the eclipse safely?
    • Be sure your glasses or viewers are new: glasses that are more than 3 years old, or are wrinkled or scratched, won’t protect your eyes.
    • Read – and follow – the instructions carefully.
    • Don’t use homemade filters or ordinary sunglasses.
    • Never look directly at the sun without eclipse glasses or solar viewers that are certified as safe. (Again, look for ISO 12312-2 to be printed on the product.) It can lead to serious injury.
    • Don’t look at the uneclipsed or partially eclipsed sun through an unfiltered camera, telescope, binoculars, or other optical device – even using your eclipse glasses or viewer. Those optical devices concentrate the solar rays, will damage your eclipse glasses or viewer, and seriously injure your eyes.

    St. Louis (Jefferson County) here, right in the middle of the path.
    We bought glasses from American Paper Optics that are CE and ISO 12312-2 certified for about $1 a pair.

    Great post Cee! We have been selling the shiznit out of proper glasses at our Eyecare office. We are also very lucky that we are 20 minutes from a prime viewing spot and we are closing for awhile to go watch!

    So I did check the library, and they do not have the glasses. Then I checked the Thousand Oaks Optical site. And if you want to get the certified glasses, in a lesser quantity to check with Lowes Hardware. So, I did check, and they do have them at the registers for under $2.00 each. So, Lowes has them.

    Here are the best U.S. cities within the eclipse's path of totality to watch the spectacular sky show:

    Salem, Oregon

    The solar eclipse starts at 9:05 a.m. PDT and totality begins at 10:17 a.m. PDT, lasting for nearly two minutes.
    The city of Salem is already making plans for the big event. The Oregon Museum of Science and Industry will host a viewing party at the State Fairgrounds in the city.

    Life Church is offering dry RV parking on a large field at its property in West Salem for people looking for a spot to watch the eclipse.

    Madras, Oregon

    The solar eclipse starts at 9:06 a.m. PDT and totality begins at 10:19 a.m. PDT, lasting for about two minutes.
    The 2017 Oregon Solarfest and eclipse viewing will take place in Madras. The festival, which runs from Aug. 18 through Aug. 21, will have a three-day lineup of music and entertainment.

    Idaho Falls, Idaho

    The solar eclipse starts at 10:15 a.m. MDT and totality begins at 11:33 a.m. MDT, lasting for just under two minutes.
    The city of Idaho Falls is planning to host many guests in the region for the celestial phenomenon. According to NASA, the city will have four designated viewing locations -- Old Butte Park, Tautphaus Park, Freeman Park and Community Park -- where there will be public restrooms, public parking and plenty of wide open space to watch the eclipse.

    Jackson, Wyoming

    The solar eclipse starts at 10:16 a.m. MDT and totality begins just before 11:35 a.m. MDT, lasting for a little over two minutes.
    The centerline of the total eclipse will pass over the southern part of Grand Teton National Park in the Jackson Hole valley, making it one of the best places in the country to experience the astronomical event.

    Steven Hawley, a former astronaut and senior manager at NASA, told ABC News he plans to travel from his home in Lawrence, Kansas, about 1,000 miles to Jackson to watch the eclipse. It will be his first time seeing a total eclipse from the ground.

    In 1979, Hawley witnessed a total solar eclipse from an airplane at an altitude of 43,000 feet.

    "We were flying through the [lunar] shadow. You could kind of see the shadow on the Earth's surface," Hawley told ABC News. "It's a unique perspective."

    Casper, Wyoming

    The solar eclipse starts at 10:22 a.m. MDT and totality begins at 11:42 a.m. MDT, lasting for a little under two-and-a-half minutes.
    The 2017 Wyoming Eclipse Festival will take place in Casper, where residents, scientists, photographers and eclipse chasers from across the globe will march to the line of totality in the city on Aug. 21. The festival will also have a lineup of special activities and programs all week long.

    Retired NASA astrophysicist and photographer Fred Espenak told ABC News he plans to travel from his home in Portal, Arizona, about 1,000 miles to Casper to speak at eclipse-related events and to watch the event. But if clear skies aren't in the forecast there that day, Espenak said he may travel west or east to another city along the path of totality to get the best view.

    "It all boils down to what the weather is going to do," Espenak told ABC News. "Any place along that path can be clear or cloudy on eclipse day."

    Lincoln, Nebraska

    The solar eclipse starts at 11:37 a.m. CDT and totality begins at 1:02 p.m. CDT, lasting for a little under a minute and a half.
    The city of Lincoln's Convention and Visitors Bureau is planning a range of events on Aug. 21. Haymarket Park, home of the Lincoln Saltdogs baseball team, will provide spectacular eclipse viewing points and interactive events as well as indoor and outdoor talks and presentations. As the eclipse approaches, the baseball game will enter an "eclipse delay" so fans and players can enjoy the rare event.

    Jefferson City, Missouri

    The solar eclipse starts at 11:46 a.m. CDT and totality begins at 1:13 p.m. CDT, lasting for roughly two-and-a-half minutes.
    Beginning Aug. 19, Jefferson will host a three-day celebration of art, astronomy and live entertainment as well as a viewing of the Aug. 21 eclipse on the Missouri State Capitol lawn and at various other locations around the city.

    Carbondale, Illinois

    NASA anticipates the total solar eclipse to last longest near Carbondale, about 100 miles southeast of St. Louis, where the sun will be completely covered for about two minutes and 40 seconds. The eclipse begins here at 11:52 a.m. CDT and totality starts at 1:20 p.m. CDT.
    Paducah, Kentucky

    The solar eclipse starts at 11:54 a.m. CDT and totality begins at 1:22 p.m. CDT, lasting for a little over two minutes.
    Madisonville, Tennessee

    The solar eclipse starts at 12:04 p.m. CDT and totality begins at 1:32 p.m. CDT, lasting for about two-and-a-half minutes.
    Nashville, Tennessee

    Nashville will be partially in the path of totality. There, the solar eclipse starts at 11:58 a.m. CDT and totality begins at 1:27 p.m. CDT, lasting for a little under two minutes.
    Nashville's Adventure Science Center will host a three-day festival packed with live music, science demonstrations, solar telescope viewing stations as well as an eclipse viewing party on Aug. 21 with a massive screen broadcasting NASA footage of the moon blocking the sun.

    Clayton, Georgia

    The solar eclipse starts at 1:06 p.m. EDT and totality begins at 2:35 p.m. EDT, lasting for roughly two-and-a-half minutes.
    Rabun County, which encompasses Clayton, is planning various events in the region for those wanting to observe the eclipse from northeastern Georgia. Rabun Gap-Nacoochee School will host a viewing party the once-in-a-lifetime event.

    Columbia, South Carolina

    The solar eclipse starts at 1:13 p.m. EDT and totality begins at 2:41 p.m. EDT, lasting for two-and-a-half minutes.
    The city of Columbia will host the "Total Eclipse Weekend" from Aug. 18 to Aug. 21, featuring a long weekend of more than 80 eclipse-related festivals and events.

    Charleston, South Carolina

    Only part of Charleston will be able to see totality. There, the solar eclipse starts at 1:17 p.m. EDT and totality begins at 2:46 p.m. EDT, lasting for about a minute and a half.
    Charleston's MUSC Health Stadium will host a family-friendly eclipse viewing party complete with astronomy-related activities, a science-based kids zone, local food, drinks and entertainment. The city will also provide other viewing locations and eclipse-related activities at various parks.

    I am almost 4 hours from Clayton GA (south)! I have been studying this since you posted it, wondering how I will get to see...

    I love stuff like this, heck I let NASA message me when the space station will be close so I can watch it. I'm kinda nerdy like that!

    My understanding is that where I live the duration of the eclipse will be 2 min 34 sec.
    My town has events planned and is expecting a lot of visitors.

    The point is that some companies are making fake glasses with fake ISO symbols.
