Total solar eclipse: What you need to know

Posted July 22, 2017

With just a month left to go, the buzz in anticipation of the Great American Eclipse of 2017 is real.

With the help of an advanced 3-D radiative transfer computer model, the scientists are working to simulate the eclipse that will occur on August 21 and pass across America.

You'll have to get south of Bend, Ore., or southwest of Salem, Ore., to see the total solar eclipse.

"It's quite a big deal across that 70-mile swathe", Dcruz said.

"I understood at that moment why people chase these things around the world".

People have to be within that region to witness a total solar eclipse, she said. The last total solar eclipse that passed over the Miami Valley was more than a thousand years ago.

Researchers who studied an eclipse across Europe in 1999 found that the event lowered air temperatures by as much as 5°F across the path of totality.

First of all, what is a solar eclipse? Anything more than a quick solar glance can result in permanent damage - literally burning a hole into your eye.

Viewing with Protection - Experts suggests that one widely available filter for safe solar viewing is number 14 welder's glass.

Brian Sievers, physics teacher at Shepard High School in Palos Heights, said the best place to view the total eclipse in IL is in Carbondale.

Degenkolb complained that Matthews did not hold his line in the sprint, but the Australian was adamant he raced fairly. I didn't change my line, I sprinted in a straight line.

When you look up at the sky to marvel at the spectacular sight, you'll need to do it safely. Even a sliver of the sun, is too bright for our eyes. Study maps in the area where you plan to see the eclipse in case you need to drive quickly to a new location. You'd do best to avoid that since there is no cure for solar retinopathy.

The length of the totality actually varies from eclipse to eclipse.

For a brief moment, day will turn to night. No problem. We'll be able to see a partial solar eclipse right here at home.

Where to lookSo, you've got your glasses. A little further east, Orient will see a maximum eclipse of about 85.9 percent at 10:26 a.m.

"Someone can blind themselves looking directly at the sun, even with only 15 percent visible sunlight", he said.

If you don't own a DSLR problem.

On the 21st of August this year, the sun will go dark in the middle of the afternoon.

Rest assured that the world's media will be flooded with professional captures of the totality as soon as the event is over, so you might as well just sit back and enjoy the spectacle. Especially fanatical groups have even chartered a plane to fly alongside the path of totality to extend their viewing time.

"While the solar eclipse is a once-in-a-lifetime event, the beauty of the Tennessee River Valley is timeless", says Julie Graham, Tennessee River Valley Mapguide site administrator.
