Millions of people will soon travel to a narrow strip in America to witness a rare event: a total solar eclipse. On 21 August, many will look up to the sky to witness this phenomenon — will you be one of them? In the following shortened excerpt from Totality: The Great American Eclipses of and , learn what types of eyewear you should be using to watch the Sun disappear, when you can do away with eye protection completely, and other ways to best view this event. You would never think of staring at the Sun without eye protection on an ordinary day.

Eye Safety During Solar Eclipses

Remember to use safe solar eclipse glasses and other equipment during the partial phases, and soak up the darkness during totality!

In fact, you've probably been told that by lots of reputable sources including our own Space. A total solar eclipse happens when the central disk of the sun is completely covered by the moon. But total solar eclipses are a much rarer sight. A joint statement from NASA and the four other organizations says that with the right information, skywatchers can safely view the total solar eclipse in its full glory with the naked eye.

Anyone in the United States on Aug. But only those people in what's known as the " path of totality " will see a total solar eclipse. For the Aug. This is truly one of nature's most awesome sights. But in order to see this awesome natural sight, skywatchers need to know how to view the eclipse safely. Looking directly at the sun without eye protection can cause serious eye damage or blindness.

During a partial solar eclipse, people often use pinhole cameras to watch the progress of the moon across the sun's surface pinhole cameras are easy to make at home. This is an "indirect" way of observing the sun, because the viewer sees only a projection of the sun and the moon. The "lenses" of solar-viewing glasses are made from special-purpose solar filters that are hundreds of thousands of times darker than regular sunglasses, according to Rick Fienberg, press officer for the American Astronomical Society AAS.

These glasses are so dark that the face of the sun should be the only thing visible through them, Fienberg said. Solar-viewing glasses can be used to view a solar eclipse, or to look for sunspots on the sun's surface. But beware! Some older solar-viewing glasses may meet previous standards for eye protection, but not the new international standard, Fienberg said. Click any of the company links to find out how to purchase eclipse glasses.

Fienberg said some manufacturers are making solar-viewing glasses with plastic frames, rather than the traditional paper frames. While these may look like regular sunglasses, do not be mistaken. Sunglasses are never a substitute for solar-viewing glasses. Fienberg said some people may even try to view the sun through two or three pairs of sunglasses in an attempt to replicate the protective power of real solar-viewing glasses; however, even multiple pairs of sunglasses will not protect your eyes from sun damage.

Telescopes, cameras, binoculars and other optical devices need their own solar filters. Solar-viewing glasses are not a substitute for a proper solar filter on magnification devices. Never view the disk of the sun through a telescope, binoculars or camera without a proper solar filter. Solar-viewing glasses are not powerful enough to protect your eyes from magnified sunlight. Even if you are wearing solar-viewing glasses, viewing the disk of the sun through a magnification device will result in serious eye damage if the device is not equipped with a proper solar filter, according to the viewing safety sheet.

Fienberg said there is no need for skywatchers to use a telescope during the eclipse, but a pair of binoculars can be helpful during totality. But, per the recommendations, do not attempt to look at the disk of the sun through binoculars, even with solar-viewing glasses. Now that you have some general information about how to view the sun safely, here are NASA and the AAS' recommendations for how to safely view the total solar eclipse with the naked eye.

Again, these tips come from NASA's safety information sheet here. Viewers who are looking at the eclipse with solar-viewing glasses will be able to see when the sun's face is completely obscured by the moon because, once again, the only light that can penetrate these solar-viewing glasses is the light from the sun's disk.

Viewers will be able to observe the moon creep slowly over the sun's disk and eventually cover the sun entirely. In the moments before totality, viewers looking through their solar-viewing glasses will see a crescent of light from the sun growing thinner and thinner as the moon progresses over its face.

In the last few seconds just before the disk of the sun is entirely covered by the moon, the crescent will break up into a series of small dots of light that look like beads on a string typically there are about three to eight such dots, according to Fienberg. Once the last bead disappears, the face of the sun has been covered by the moon, and totality has begun. The safety information sheet also recommends that viewers be aware of another drastic change that takes place during a total solar eclipse: L ight levels drop dramatically, as if the world had suddenly been plunged into dusk.

This is one indicator that totality has begun and that it is safe to take off your eclipse glasses. When should you put your glasses back on? The official recommendations from the agencies suggest that viewers put their solar-viewing glasses back on before any part of the sun's disk becomes visible again.

To anticipate when the disk of the sun will reappear, viewers should first be aware of about how long the total eclipse should last where they are standing — the total eclipse will last, at most, about 2 minutes and 40 seconds. The nearer that viewers are to the edge of the path of totality, the shorter the total eclipse will be.

Viewers who want to observe the total solar eclipse with the naked eye should try to move closer to the center of the path so that there is ample time to observe the eclipse safely. Fienberg said that viewers should be aware of the moon moving across the surface of the sun during totality. The side of the sun that was the last to disappear behind the moon will be opposite to the side that is first to reappear.

On the side of the moon where the sun will reappear first, viewers should look out for the "reddish hue" of the chromosphere, the layer of the sun's atmosphere that is closest to its surface. The sun will begin to reappear just as it disappeared — first as dots of light. If a dot of sunlight appears on the edge of the moon, it means totality is complete. The AAS and NASA are expecting huge crowds to flock to the path of totality for the total solar eclipse, including more experienced eclipse watchers.

These seasoned observers may start shouting "Baily's beads! As the eclipse nears totality, people may also shout "Diamond ring! Together, they will look like a diamond ring. Experienced observers may decide to look at the eclipse with the naked eye just before the sun is completely covered by the moon, when the diamond ring appears. Diamond ring! Filters off!

The reason they're not is because it only lasts a second or so. And then it's gone and you see the corona, and it's dark and it's spectacular and beautiful. While you may see some people removing their solar-viewing glasses before the eclipse reaches totality, this is not recommended by the official eclipse-viewing guide from NASA and the AAS.

While Fienberg is adamant about eclipse-viewing safety, he is equally insistent that skywatchers should view the total solar eclipse with the naked eye, because the experience is like nothing else on Earth. The sun's atmosphere "is always there, but we can't see it," Fienberg said. And it is just magnificently beautiful. It's awesome in the truest sense of the word. It just makes your jaw drop. The first time you see it, you just can't believe how beautiful it is.

And it brings tears to people's eyes. The sun's atmosphere isn't a uniform haze like the Earth's atmosphere, Fienberg said. It's "a tangle of streamers and jets and loops and twists, and all kinds of stuff, because it's controlled entirely by the sun's magnetic field, which is very tangled and twisted.

The chromosphere, the atmosphere closest to the sun's surface, "is an unbelievably beautiful, pure magenta-red color. If the chromosphere is active and there are eruptions going on on the edge of the sun, you'll see prominences — they look like flames or jets of this really beautiful hot-pink magenta gas that are extending out beyond the silhouette of the moon," he said.

Fienberg is an eclipse chaser; he has traveled all over the world to see total solar eclipses. On his very first eclipse-viewing trip, before seeing the event, he met a man who hosted a music radio show in the city where Fienberg lives. The radio host was an eclipse chaser, and Fienberg said he'd never heard the host talk about astronomy on his show. This about being out in nature and being one with the universe — I mean, it sounds silly!

But you really feel like you're just part of it all and you're privileged to be able to see such a beautiful thing. Follow Calla Cofield callacofield. Original article on Space.

Bengaluru : A day after Christmas, on 26 December, the moon will gently glide in between the Earth and Sun, blocking the view of Sun completely and leaving only its outer edges to form a bright ring around the moon. This is called an annular solar eclipse and will be visible in several countries in Asia, including India. The annular ring will, however, be seen only in parts of Karnataka, Kerala and Tamil Nadu. Kannur in Kerala will be the first city in India where the ring will be visible. The rest of the country will see it as a regular partial eclipse. The annular eclipse will be visible in India at 9. The eclipse will exit India at 9. The entire eclipse event will last a total of 3 hours and 13 minutes, although not all of it will be visible from India.
