Hopkinsville, in Christian County, will be the point of "greatest eclipse" with 2 minutes and 40 seconds of totality on August 21 at 1:24 p.m. CDT.
While many people want a good, tight shot of the eclipse, keep a bigger picture in mind. Specialty solar glasses that meet the worldwide standard ISO 12312-2 for direct observation of the sun should be used.

It has been reported during solar eclipses that animals change behavior and may be startled or confused. However, in Madison - where a maximum of 85 percent of the sun will be blocked by the moon at about 1:15 p.m. - that won't be an option. Here on the Keweenaw Peninsula, we will have a 71 percent eclipse.
There are alternative methods to indirectly view the partially eclipsed sun. As the total eclipse approaches, if you are up a little in elevation or can see a bit of a distance to the horizon, you will see the total eclipse shadow fast approaching from the northwest. The eclipse will move from the West Coast to the East Coast, ending near Columbia, South Carolina, at 2:44 p.m. According to Nasa's solar scientist Mitzi Adams, plants will be affected by the eclipse. It's called solar retinopathy, and it's like a sunburn on your retina, and causes spots in your vision that may or may not go away.
As a result, demand is soaring for safe glasses for viewing it. We've got our eclipse glasses, and we're looking forward to it.
