Total Solar Eclipse passing through Crossville August 21-You don't want to miss it.

A big event passing through Crossville on August 21 as it speeds along at 1600 MPH, a total eclipse of the sun.

I would strongly encourage you not to miss seeing this event since it is coming right through Crossville and should be spectacular to see unless the weather doesn't cooperate.

total eclipse.  Most of the rest of the US will see
at least a partial eclipse.

I see it being called a “once in a lifetime opportunity” and for some that might be the case, but it will be a twice in a lifetime opportunity for me. I can talk about the eclipse because I have already seen one previously and it is, without a doubt, one of the most impressive astronomical events you will ever see. You will need special glasses, welding glass or completely exposed and processed black and white film to safely look at the eclipse except during the time of totality.
The gray area is the total eclipse coverage area and 
the blue line is the center of the totality path.
Everywhere in the gray will see a total eclipse of the sun.

The eclipse starts about noon and becomes total at about 1:30 PM CDT. The eclipse remains total for 2 and one-half minutes. The sky will get dark and the temperature could even drop and if you are near any roosters, they will crow as if it is morning when the sun starts to come back out from behind the moon. The eclipse happens when the moon passes in front of the sun casting its shadow on the earth.

Up until the eclipse becomes total, eye protection is required to look at the sun. In addition to the protective glasses there are ways to watch the eclipse using pinholes or reversed binoculars projecting on paper etc. Check out some resource links below explaining those techniques. During the period of totality you can safely look at the sun because it will be completely blocked by the moon for that 2 and a half minutes in Crossville.

March 7, 1970 when I was 13 years old, my parents took us to South Carolina to see the total eclipse that happened then. We were driving through a fairly rural part of South Carolina when we stopped to see the eclipse. We had fully exposed film that we used at the time for watching the eclipse through and I was a rank amateur photographer using an old Kodak 127 film Brownie Fiesta camera to shoot pictures.

For a great deal on a great vehicle

The eclipse was a fascinating event. Things began to get darker as more and more of the sun was covered by the moon until the eclipse became total and it was almost like dusk. The most interesting thing was right before it went total there is a point where only a tiny part of the sun remains unblocked by the moon and it creates what is called the “diamond ring effect.” You see just a bit of light around the sun and at one end a bright part of the sun that looks like a stone. You have to be quick to see it as it only lasts a very short time. There is another chance to catch “the diamond ring” comes as the totality ends and the sun starts to emerge from behind the moon.

I hope you'll be watching. I know I will be.

keep your eyes open during the partial phases that lead up to and follow it. As you view the beginning through a safe solar filter, the universe will set your mind at ease when you see the Moon take the first notch out of the Sun’s disk. Around the three-quarters mark, you’ll start to notice that shadows are getting sharper. The reason is that the Sun’s disk is shrinking, literally approaching a point, and a smaller light source produces better-defined shadows. At about 85 percent coverage, someone you’re with will see Venus 34° west-northwest of the Sun. If any trees live at your site, you may see their leaves act like pinhole cameras as hundreds of crescent Suns appear in their shadows.

Below are some safe ways to view the eclipse.
