The Effingham County school system has declared Monday, Aug. 21, an inclement weather day in anticipation of the total solar eclipse. The eclipse with cross the entire country from coast-to-coast for the first time since 1918. From there, the deep shadow of the moon will pass over parts of Oregon, Idaho, Wyoming, Montana, Nebraska, Iowa, Kansas, Missouri, Illinois, Kentucky, Tennessee, Georgia, North Carolina and SC before ending at 4:09 p.m. ET, NASA said. The eclipse will last longest near Carbondale, Illinois: two minutes and 44 seconds.
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.
The effect of a flawless total eclipse depends on the closeness of the Moon to the Earth. The eclipse will reach its maximum over us at around 2:24 PM.
"What I am telling people is, it's still the sun". Although it is safe to look up at a total solar eclipse (when the solar disk is completely covered by the moon) with the naked eye, you'll need special solar-viewing glasses before and after totality, when part of the solar disk is visible.
As the total solar eclipse approaches, demand for safe viewing glasses has spiked and experts are warning the public to be wary of risky knockoffs.
"We used to say that you should look for evidence that they comply with the ISO 12312-2 worldwide safety standard for filters for direct viewing of the sun", according to a statement on the American Astronomical Society's website. Here is step by step video on how to make one.
The American Astronomical Society Task Force has been working put together a list of well known solar-filter brands that meet the safety standard. All those on the above list are approved.
Viewing the eclipse with the right glasses is important, Kriewald said, adding the proper glasses will block out room lighting.
The Center for Astrophysics' new app, Eclipse 2017, comes with several features to prepare, learn, and watch the eclipse that will travel across the United States on August 21.
The death of Christ was said to have been followed by a period of darkness during the day, which some historians believe may have been an eclipse that took place in 29 CE.
The best bet for pictures is to get a telephoto lens for your camera. If you miss this one, there won't be another chance in the continental United States until 2024. "The good news is that many teachers are planning exciting ways to educate kids about the eclipse during the first few weeks of school".
"Even very dark ones are not safe for looking directly at the sun; they transmit many thousands of times too much sunlight", AAS says.
Be prepared for spotty cell phone coverage in a few locations. "It will also be nearly at its highest point (the sun is high in the sky when it is directly south, 180 deg)", Speck said. So when it blocks out the sun we can actually see the sun's atmosphere, the corona. If you're lucky enough to live along the path of totality, you'll have a front seat to the greatest show on Earth - a rare event many say is life-changing. The Nantucket Maria Mitchell Association will also be offering a number of programs and workshops to celebrate the occasion with a week of fun leading to the eclipse. Everyone is encouraged to bring them back on August 21 and enjoy the free activities planned for the solar eclipse.
A partial eclipse will be visible across North America, as well as in parts of South America, Africa and Europe.
