This is the first such eclipse to travel the width of the U.S.in 99 years, and not until 2024 will another total solar eclipse cross the USA from coast to coast.
The chromosphere and corona - During a total eclipse, the moon blocks out the photosphere, the part of the sun we usually see that outshines the sun's chromosphere and corona.
Huge numbers of eclipse glasses are being sold amid warnings not to look directly at the Sun, because it can cause severe damage to your eyes. "With the eclipse a month away today, it's prudent to practice ahead of time".
The eclipse will soar right over the St. Louis area.
NASA Scientist Noah Petro adds, "Do not look at the sun with your normal daily sun glasses".
If you can't get your hands on glasses approved by NASA, it's better to just skip the sunny stare-down and opt for a more DIY eclipse-viewing plan. Craig Linde will explain how to safely observe the eclipse using tools such as filters.
Granted, you always can stay indoors and simply catch the solar eclipse live online.
NASA says the only safe way to look at the eclipse is with special objective "eclipse glasses".
The path of totality for the August 21 eclipse begins, for some inexplicable reason, in Lincoln Beach, Oregon, of all places. The school district purchased 12,000 eclipse viewing glasses.
The presentation, titled "Eclipse 101: Preparing for Darkness at Noon", is scheduled for 2 p.m. August 5 as part of the museum's "Solar Eclipse Day" event.
Wherever you see the eclipse from, you'll be witnessing something incredibly rare. Two-thirds of the time, it's not, and there's only a partial eclipse. The last time a solar eclipse occurred in the contiguous United State was on February 26, 1979, and it won't happen again until April 8, 2024.
Chattahoochee Nature Center will be providing eclipse glasses while supplies last.
It is not safe to look at the uneclipsed or partially eclipsed sun through regular sunglasses, unfiltered telescopes or magnifiers or cameras, polarizing filters, CDs/DVDs or space blankets. Cleveland will have 1 minute and 2 seconds of darkness and Charleston is slated to see 2 minutes and 4 seconds of totality.
