Forget Sunglasses: How to Keep Your Eyes Safe During the Solar Eclipse


For the first time in almost four decades, the United States will be affected by a total solar eclipse on August 21.

During that solar eclipse, which crossed Manhattan just above 96th Street on January 24, 1925 as temperatures hovered around 9 degrees Fahrenheit (minus 12.8 degrees Celsius), researchers went all out to measure the celestial event. In any one location, a total solar eclipse occurs, on average, every 375 years.

The ancient Vikings, he said, believed that giant wolves chased the sun and moon and when they caught them an eclipse happened.

The best of the apps are the Smithsonian's Eclipse 2017 and Eclipse Safari, which offer science history, and best practices for why you need to wear your solar glasses during the time of totality, respectively.

The map shows the swath along the path of total eclipse, where the sun will be fully covered, in blue ranging from deep to light.

The path goes just south of the IN border, which means Fort Wayne will experience a partial solar eclipse with about 85 percent of the sun blocked, Science Central Executive Director Martin S. Fisher said IN a news release.

Fayetteville Public Library - The library is giving away the glasses while supplies last during an eclipse prep event on Sunday (Aug. 13) from 1:30-4 p.m.

While a last-minute rush has left many dealers out of stock two weeks before the big day, the good news is that US astronomy buffs have to wait only seven more years for the next total solar eclipse over North America, in April 2024.

Think you can get by without those amusing looking eclipse glasses?

While no data exists for how many made-for-eclipse eyeglasses are in circulation overall, shady distributors of purportedly solar-safe shades abound on the Internet, Fienberg said.

Visitors can pick up a limited number of the free glasses at Penn Dixie during normal business hours. There is a narrow band, which extends from Salem, Oregon to Charleston, South Carolina, where observers will experience a total eclipse. The Bravas and Ragin' Cajun food trucks also will be parked nearby so people can enjoy food while they watch. Most cameras, and even many camera phones, have adjustable exposures, which can help you darken or lighten your image during the tricky eclipse lighting. Only use a telescope or binoculars if they are fitted with reliable solar filters created to fit directly on the instruments and the operator knows how to use them. If it is scratched or damaged, throw it away.

The AAS and NASA have posted a list of reputable solar filter brands, retail distributors and online dealers.

Forget sunglasses. Certified eclipse glasses or hand-held viewers are a must for direct viewing. Special eclipse glasses, ISO 12312-2 compliant, are needed for viewing, according to NASA. If you look (always through a solar filter), perhaps at five- or 10-minute intervals, you will be able to see that a bite has been taken out of the sun.
