Solar eclipse glasses almost sold out

On Aug. 21, the moon's shadow will block the sun from view in what many are calling "The Great American Eclipse".

"The Great American Eclipse" will cast a shadow over the whole country, moving diagonally from OR in the northwest to SC in the southeast.

Why is this a big deal? Bill Radke talks to Erika Harnett, research associate professor of earth and space science at the University of Washington about all things solar eclipse. "We have a whole bunch of different stuff this time, not just solar eclipse stuff".

Monday is also National Senior Citizen Day, and the Flower Mound Senior Center is celebrating with a Solar Eclipse Patio Party at 1 p.m. Attendees can enjoy live music, dancing, an ice cream sundae bar and safety glasses.

In Grifton the moon will eclipse approximately 92 percent of the sun at 2:47 p.m. "The light from the sun is so powerful that this small amount of the sun will damage your eyes and cause blindness if you look at it directly-even if you look at it for only a few seconds".

Not to worry. If clouds are scattered, we'd still be able to get the gist of the moon blocking out part of the sun but in occasional fashion. "They can be looking up and who knows what could happen". Even with a partial eclipse, solar viewers are still necessary!

For places that are getting totality, like in OR or SC, that spectacular highlight of the eclipse experience only happens for roughly 2½ minutes. The eclipse should reach the Valley by 1:17 p.m. and end around 3:57 p.m. The hole is where the sun will shine through.

Depending on your location, a partial eclipse, during which the moon covers a portion of the sun, lasts from two to three hours.

The image will show the actual eclipse.

"So the longer the tube the larger the image of the sun", Leake says.

Boyce and others are interested in learning more about the sun's corona, the layer of plasma surrounding the star.

How should I watch it? .

But before you decide to spend much of Monday hiding under your bed, the ASRS also says it's perfectly safe to view the eclipse directly either by wearing protective eclipse glasses or indirectly using a pinhole projection contraption, just like the aforementioned pizza-box version.
