This path, where the moon will completely cover the sun and the corona or halo can be seen, will stretch from Lincoln Beach, Oregon to Charleston, South Carolina. As the moon crosses between the earth and sun, the sun will appear to change shape as it will be partially blocked from our view. Without proper eye protection, you can suffer "eclipse blindness" - a serious injury in which the eye's retina is damaged by solar radiation - within seconds of starring at the sun, according to the American Optometric Association.
If you're planning on watching the eclipse in its path of totality, you'll be able to look up in the moments of the total eclipse. You most likely won't go blind but your vision will be impaired.
"For an unmagnified view, the eclipse glasses are probably the most simple, straightforward, and easiest to use and readily available this time around".
10 from 6-7:30 p.m., Curtis Memorial Library and Cornerstones of Science will host an informational program on the upcoming eclipse. Solar eclipses are fairly common - more so than lunar eclipses - occurring about two to four times per year. He's cautioning people making the trip to Nebraska or Missouri to watch a total eclipse to be ready for spotty cell phone coverage, and to be self-sufficient that day.
"But you've got to be careful", said optometrist Myron Wasiuta.
The eclipse on August 21 will last just two-and-a-half minutes for most people, but for the researchers in the WB-57F jets, it is expected to last over seven minutes. "Look anywhere there's a pinhole image, where the sun shines through a little crevice or something like that".
The sun can not be safely viewed with the naked eye. You can see the ghostly halo of the sun's atmosphere around the moon, poking out.
"Solar eclipses themselves are not rare, but the chance of having one pass over where you live is really special", said Porter. This event, a total solar eclipse, will be "turning daylight into twilight, causing the temperature drop rapidly".
Due to the fact Everly is so passionate about astronomy, he found a way to buy the special glasses from the Astronomical League cheap enough to give them to the community for free.
