It is due to cross the U.S. from west to east, passing through parts of the following 14 states: Oregon, Idaho, Wyoming, Montana, Nebraska, Iowa, Kansas, Missouri, Illinois, Kentucky, Tennessee, Georgia, and North and SC.
On Monday 21 August a solar eclipse is due for those directly in the Moon's shadow on Earth.
The celestial event Monday, a total solar eclipse, hasn't been seen in the United States since 1979.
Courtesy photo On Monday, Aug. 21, there will be an eclipse of the sun that will occur along a path stretching from OR to SC. Because the sun and moon appear the same size, the sun is momentarily blocked, turning the sky dark and leaving a corona of light around the moon. Eclipse viewers should use special-purpose solar filters, such as eclipse glasses or hand-held solar viewers purchased from authorized dealers of such products.
There have also been questions about the safety of using welders' goggles or a welding mask to look at the eclipse.
Thompson said there is a misconception that a person can watch the eclipse while looking through the hole in the pinhole device, but that is not safe. Pending clear skies, at 1:31 p.m. you'll see the eclipse for just a few minutes. The millions of folks who live outside this narrow band will experience various stages of a partial solar eclipse, meaning the moon will only block out a portion of the sun.
The path of totality will begin near Lincoln City, Oregon, as the lunar shadow makes its way into the US. An eclipse viewing party that had been scheduled in Yountville was cancelled after organizers were told that the solar eclipse viewing glasses that were ordered for the event had been recalled.
If you opt for specially designed glasses with solar filters, look for the "ISO 12312-2" designation that indicates they meet worldwide safety standards, Rao noted. The app also comes with an eclipse calendar that will let you view the past and future eclipses.
You can learn about research of the sun at the Big Bear Solar Observatory here. "By worldwide standards, they are so black when you put them on you can not see any light, through these you look at the sun it's a little orange ball".
"Because the Moon's orbit is tipped about 5 degrees to the Earth's orbit around the Sun", Dr Espenak says.
"At no time in AZ will it be safe to look at the Sun without filters specially designed for solar viewing", said Dutkevitch. Looking at the sun with substandard glasses may cause permanent damage to your eyes. The realities they offer upon meditation should make one acknowledge the unforgiving consequences for our children and grandchildren if we plunder and pollute this planet with such great abandon.
