The path of totality will be around 60 miles wide.

A partial eclipse will appear throughout North America. Here are some frequently asked questions about the upcoming phenomena.

It will get darker outside, but not completely dark. The closer you are to the totality band, the more the sun's disk will be covered up by the moon.

"I think (this solar eclipse) is pretty cool", Kobilka said.

The recalls also have had far-reaching effects on the makers of legitimate eclipse glasses and filters, who say they are now dealing with extra-anxious customers. Sunglasses do not provide enough protection. It has notified buyers of unverified glasses and warned them not to use them to view the sun or the eclipse.

She said a pin hole camera is safe because you can't always trust your kids to wear their glasses. Use the solar eclipse glasses over regular ones. These work by refocusing the sun's light into a dark space... to make the eclipse more pronounced.

"The market has been overrun with counterfeits and fakes, and many of them were being sold on Amazon", said Richard Fienberg, a spokesman for the AAS.

"I didn't want to run out of glasses and have people miss the experience or put themselves in danger", Giardino said.

Only during totality is it safe to take off eclipse glasses and view with binoculars and telescopes. NASA also suggests you inspect your filter before putting it on, and discard it if it has any scratches or damages.

Eclipse glasses can be worn directly over your prescription glasses or with contacts.

The site notes that most arc welders use a shade much less than No. 14.

A simulation of every total solar eclipse over several thousand years by Belgian astronomer Jean Meeus has shown that, on average, the time between total eclipses in any location on Earth is 375 years.

"Instinctively, we don't look at the sun", Houser said. The 12 million people who live there can view the eclipse at its fullest merely by walking outside and looking up, weather permitting. Never mind that looking at the sun for just a few seconds can cause serious eye damage. "I'm telling people, 'If you have a family of three or four, not everyone has to have their own pair - you can pass it around'".

Some might take issue with that prediction, citing a solar eclipse visible over parts of India, Nepal, Bangladesh and central China in July 2009.

Yes, but it will be indirect. You can look through them safely, but not if they're counterfeit. Pinhole projectors are an easy way to indirectly view the eclipse.

And in many ways, Monday's eclipse is a gift from the universe.

Will clouds be an issue on August 21? .

Also, 55 different teams are taking part in the Ballooning Project which will involve video being streamed from special balloons which have been sent into the sky. Afternoon showers and thunderstorms are possible as well.

Of course, the eclipse will be carried LIVE on many of your cable network and local TV stations. I remember it best in 1991 in Baja California: a cool breeze came with the disappearing sun and a sense of relaxation, the way you feel after sunset at the end of a steamy day. That shouldn't change during an eclipse. A Solar Eclipse Distillery Tours will be offered from 2 p.m.to 3 p.m. It'll be the first to span the U.S.in almost a century, and people are already going insane, ordering eclipse glasses en masse, traveling to the best viewing spots and throwing all-day parties.
