But suddenly your day changes. "It will look like a big bite taken out of the sun", he said. You watch mesmerized as the son disappears and you think that this is some sort of omen from the gods.
Merlo also explains prices can range from a couple cents to a couple of dollars depending on how many you order but he recommends ordering glasses as soon as possible as they are in high demand, in fact many places in the Tri-State are still sold out. When the moon covers the sun completely, day turns to twilight in minutes, animals act weird, people scream and cry - or so I've heard. "My father was an artist, and he always challenged me to look at things from different perspectives and use all of our senses". Apparently, the communities in the swath of the total eclipse are milking it for all it's worth. That makes no difference when it comes to looking at it. Don't let the requisite warnings scare you away from witnessing this singular spectacle!
NASA is funding several ground-based science investigations across the USA that will use the eclipse as a ready-made experiment, and three of these will look to the ionosphere in order to improve our understanding of the Sun's relationship to this region, where satellites orbit and radio signals are reflected back toward the Earth.
The mechanism that blocks out the sun in a coronagraph also obstructs views of the sun's atmosphere closer to its surface, McCall said. The optical device concentrates the sun's light, which can damage the solar viewer and then your eyes. It is imperative that the welding hood houses a #14 or darker filter.
As a result, demand is soaring for safe glasses for viewing it.
If you want a more expensive option, try number 14 welder's glass goggles. But if you're not wearing certified eclipse glasses, you could be in danger of damaging your eyes.
NASA to study Earth's ionosphere during total solar eclipse
Merlo recommends people to use camera and telescope solar filters too as staring straight into the sun through a lens of a camera has potential to permanently damage the eye.
The next total solar eclipse after August 21 will be on April 8, 2024. Never look through a telescope without a solar filter on the large end of the scope. "The little spaces between your fingers will project a grid of small images on the ground, showing the sun as a crescent during the partial phases of the eclipse". In 1878, a total solar eclipse crossed the American West south into the Gulf of Mexico.
How can we safely view the eclipse? You know, the one we're supposed to wear to protect our eyes from the blazing sun.
"It's going to be hard to beat, frankly", says Thomas Zurbuchen, head of NASA's science mission office. For me, the rule is simple. don't look. Use the hashtag #Eclipse2017 and tag @NASAGoddard to connect your photos on social media to those taken around the country and share them with NASA.
He says this time around, he'll watch the eclipse on TV.
