A total solar eclipse on 21 August


A total solar eclipse is expected to occur after nearly 85 years, on 21 August for people watching from parts of United States of America.

For many, the eclipse will be a once-in-a-lifetime event. The last time a total eclipse crossed the entire contiguous US was in 1932, though there was an eclipse in 1970 that passed along the east coast.

The total solar eclipse will darken skies, drop temperatures and reveal the solar corona – the hazy aura of light that surrounds the Sun, which is usually invisible to the naked eye.

A total solar eclipse, in which the moon entirely blocks the sun, will last for nearly 3 minutes, depending on where in the country you watch.

Also, a partial eclipse will last for two to three hours and be visible to everyone in North America.
In the meantime, NASA is alerting people about unsafe eclipse-viewing glasses as parts of the country prepare for a solar eclipse.

NASA warns that one shouldn’t look at the sun, even during partial and full eclipses, through a camera or ordinary sunglasses, NASA says.

“The only safe way to look directly at the eclipsed or partially eclipsed sun is through special-purpose solar filters,” federal websites say, pointing to eclipse glasses and handheld solar viewers as examples of proper devices.

For eclipse glasses, the federal government recommends that people use American Paper Optics, Rainbow Symphony, Thousand Oaks Optical or TSE 17.

Even when wearing eclipse glasses, one should not look at the sun through a camera, telescope, binoculars or other devices, because you could be seriously injured.

Eclipse glasses are unsafe after three years, according to NASA, and shouldn’t have scratches or be wrinkled.

NASA also instructs people to use eclipse glasses that have an ISO international standard icon with reference number 12312-2.
