How to find eclipse glasses and avoid fakes

With a start time of 11:15 a.m., the eclipse will reach its peak at about 1:15 p.m. No changes will be made for the flow of traffic.

It will be the first total solar eclipse that has been visible in the continental U.S.in more than three decades.

Here's a handy map of the national wildlife refuges taking visitors on the day of the 2017 solar eclipse.

On August 21, the moon will pass between the sun and Earth for the first total solar eclipse visible in all 50 states in almost 100 years.

While our neighbors in parts of OR and Idaho will be able to witness the total phenomenon, Seattle's view is nothing to scoff at: For about two minutes, 93 percent of the sun will be blocked (no corona for us, unfortunately) at 10:20 a.m.

Damage to the eye from an eclipse impacts the most acute, precise vision in the central part of the eye, what you would use to read.

"Path of totality is what that's called", Patrick said.

If you haven't heard about the total solar eclipse coming to America this summer - then perhaps you've been in the dark. Beginning at 11:45 am EDT (3:45 pm UTC), the webcast from Southern Illinois University in Carbondale, Illinois, will track the eclipse from OR to SC.

It is NEVER safe to look directly at the sun, even during an eclipse, so if you plan to watch you will need special eyeglasses or equipment.

"If you keep looking at the sun damage can build up and you can hurt yourself", Dr. Jason Comander of Massachusetts Eye and Ear said. However, only about 0.1 percent of the earth's surface will see each eclipse. "The last eclipse on Mainland US was in 1979, but that was in the NW US". She has vivid memories of a March day in 1970, standing on the shore of a beach in Nantucket, watching a solar eclipse with a group of friends from Wellesley College, where she was a first-year student.

In Sisters, the view is 34 seconds; in Huntington, it's two minutes, 9 seconds.

And here's a link to NASA's complete guide to safely viewing the solar eclipse. During a partial eclipse, the sun basically looks like a bite has been taken out of it, but at the time of totality - when the moon passes fully in front of the sun - it's fully obscured. The glasses should not allow anything through except light from the sun or something similarly bright, such as a bright halogen light bulb, according to the society. However, the eclipse will make it easy to spot Mercury, a planet that can be tricky to spot due to its close proximity to the sun.

Once you've found the best place to see the solar eclipse, you'll need to protect your eyes. "It's going to be about a 75 percent blockage of the sun which is still pretty good", she said. "But now the marketplace is being flooded by counterfeit eclipse glasses that are labeled as if they're ISO-compliant when in fact, they are not".

"Even at maximum eclipse it is not safe to look directly at the sun", Violet Mager, assistant professor of physics and astronomy at Penn State Wilkes-Barre, said in a statement.
