when will there be another total eclipse in the southern united states?

There will be an annular eclipse on may 20, 2012 that will be visible before sunset in northern California and Nevada.

Aug 21 2017: Total solar eclipse, which will pass directly through the continental U.S, beginning around 9 am to 1 pm depending on the location. This should be visible throughout all of North America, but the umbra will pass through the states: Oregon, Idaho, Wyoming, Nebraska, Missouri, Kentucky, Tennessee, and South Carolina.

This should be pretty darn spectacular, and worth a little driving to see the totality.

Here is a link where you can research all sun and lunar eclipses. It is NASA's site and very informative.

I went through 2007 then 2008 but found nothing that will be visible for the southern part of the U.S.

NASA site has the eclipses listed through 2010.

I'm unable due to the time to research it for you. But if you get on NASA's site it will not take you too long to find your answer.

Not any time soon.

Total lunar eclipse Aug 28 2007, visible in Africa and Europe.

Total lunar eclipse Feb 21, 2008, visible in Asia.
