How to Watch the 'Ring of Fire' Solar Eclipse This Week

Solar eclipse to be visible in Derry today

Thursday's weather conditions are flawless to watch the morning's partial eclipse of the sun, but experts warn, only people with proper eclipse glasses should do so.

A total solar eclipse, such as the Great American Eclipse in 2017, happens when the moon is close enough to Earth to completely cover the sun.

Instead, skywatchers can use solar eclipse glasses, which "block 100 percent of the Sun's harmful ultraviolet and infrared rays and 99.99 percent of intense visible light", said Paulo Aur, chief financial officer and chief operating officer at American Paper Optics, which manufactures solar eclipse glasses.

2021's hottest celestial event will see a whopping 60 countries witness a chunk taken out of the sun, as the moon passes between the earth and the sun. While an annular eclipse is only visible in a narrow strip along the surface of our planet, where the moon aligns perfectly with the sun, observers in a much wider area can see part of the sun blocked by the moon.

Viewing the eclipse with the naked eye can be hazardous as a result of the potential damage the sun can cause to the eyes.

Very few people will be able to catch that, but people in the eastern USA should be able to see a partial eclipse at dawn.

In other places, including parts of the American East and northern Alaska, much of Canada, and parts of the Caribbean, Europe, Asia and northern Africa, viewers with eclipse-watching gear will see a crescent Sun, NASA reported.

The eclipse causes the sun to appear as a very bright ring, or annulus, in a phenomenon dubbed as the "ring of fire".

Tomorrow the top of the sun only will be covered in shadow. "For a sunrise eclipse, you need a position with a clear view to the horizon, like a hilltop or tall building".

Like all eclipses, to watch the "ring of fire" eclipse, protection should be worn to avoid eye damage. But if you're not careful, viewing them can put your eyes at serious risk.

It is also not wise not to look at the Sun through binoculars, telescopes or a telephoto lens on an SLR camera.

"For the big partial-eclipse sunrise in northeastern North America, a little bit of good fortune will be required".

And if you miss this event, additional opportunities to see a solar eclipse will occur in the coming years. Another method for safely viewing the eclipse is to use a pinhole projector, according to AL.com. At any given point along the path, the eclipse will be visible for a maximum length of 3 minutes and 51 seconds.
