What causes a total solar eclipse?

The closer we are to the date, the more accurate our forecast will be for the eclipse. Then again, we will be in a single auto with five kids, so who knows? Most any of the solar shades you find should work as long as they are compliant with 12312-2 worldwide safety standards.

Participants should check in at the visitor center, and are encouraged to bring lawn chairs and a picnic lunch while they watch the sun disappear behind the moon. During those brief moments - when the moon completely blocks the sun's bright face for about two minutes - the day will turn into night, making visible the otherwise hidden solar corona, the sun's outer atmosphere.

Clusters of thunderstorms - more common in the summer - pose more of a threat to block out the eclipse. Solar eclipse glasses will not provide proper protection if viewing an eclipse through a telescope or binoculars.

Neither Mercury nor Venus have moons.

Depending on the location, the totality will last anywhere from a few seconds to two minutes and 41 seconds. Parts of South America, Africa, Europe and Asia will also experience a partial eclipse.

Instead, the Japanese yen is now picking up steam against the USD, trading under ¥110 to the dollar for the first time since June. Japan is the world's biggest creditor country and there is an assumption investors there will repatriate funds in a crisis.

During the celestial event, the moon will pass between the sun and the Earth, appearing to block the sun for nearly an hour and a half.

News 18's chief meteorologist Nick Grunseth said the last total solar eclipse that occurred on Earth was March 9, 2016.

And the big question is: where can you buy solar eclipse viewing glasses? The umbral is the small shadow cast on Earth where people will be able to see a total eclipse.

The full eclipse, an area known as the "totality", will be visible in an area just south of Portland beginning at 10:15 a.m. Monday, and officials are expecting as many as one million sky-watching tourists will flock to the state.

While the eclipse will be total in some places in Tennessee (Townsend, Farragut and Maryville are in the direct path), our area will see 97 percent of the sun covered by the moon shortly before 2:30 p.m. on august 21. It's ISO 12312-2 and you should see that printed on your glasses.
