NASA issues safety warning as demand for solar eclipse glasses spikes

Share

The Solar eclipse on August 21 will affect photovoltaic generators across the United States, the EIA said.

Luckily, there are literally dozens of eclipse glasses you can use to protect your eyes from the sun's strong rays.

"The plan is we've got Central Park reserved", McLean said. Even today, certain Native American groups will not observe solar eclipses because to them the sun and moon are brother and sister.

ZEILER: Well, the most interesting site for people outside the path of totality no matter where they are in the United States is to look at the shadows of trees because the gap between the leaves of trees acts as a pinhole projector.

"For this eclipse, the longest period when the moon completely blocks the sun from any given location along the path will be about two minutes and 40 seconds", according to NASA.

Interestingly, utilities will have to be cautious because as soon as the sun returns from behind Earth's shadow, solar panels will begin to add power into the system immediately, which could overload the system if there are too many sources at the same time.

Don't worry if you can't make it down to see the total eclipse, there are still plenty of events happening in the city where you can watch a partial eclipse.

We might want to view the August 21 eclipse as a primer to an event for our lifetime, coming right here to Pennsylvania on April 8, 2024.

Warning issued over possibly eye-damaging fake eclipse glasses
On Aug. 21, a total solar eclipse will cross the continental United States from Salem, Oregon , to Charleston, South Carolina . Fisher says the total solar eclipse will go from OR all across the middle of the country to Tennessee and North Georgia to SC .

To help local families prepare for the eclipse and other incredible space phenomena, NASA Ambassador Chris Mick presented "Celestial Events of 2017" at Hardwood Creek Library 6-7 p.m. Tuesday, Aug. 1.

Are all glasses the same?

You should also avoid any eclipse glasses that are older than three years, have scratches, or are wrinkled. To enroll, most people only need to use their smartphone or ham radio and join the crowd sourced observing network. (More information about viewing the eclipse safely can be found here, on NASA's website).

NEVER look at the eclipse with the naked eye, even at 93% coverage the Sun is still very bright and can cause eye damage.

The American Astronomical Society said earlier this week that it updated its safety advice "in response to alarming reports" of unsafe "eclipse viewers" popping up online.

Some of the recommended manufacturers on the list include Baader Planetarium, Rainbow Symphony, Thousand Oaks Optical, TSE 17, and American Paper Optics. But scammers are trying to sell fake versions of those glasses.

Check for the ISO number.

Savitz said you should only wear glasses that are ISO certified, which is labeled on the side of the certified glasses. When the eclipse begins, attendees can watch the event on the scoreboard and through telescopes set up with the solar protection.

That's why Peltz, cofounder and CCO of the science-education company Mystery Science, along with his partner and CEO Keith Schacht, are working with Google to give away 15,000 glasses to schools around the U.S. in the coming weeks.
