Please allow me to refine my statement about the path of the eclipse. It appears that Knoxville may be just outside the prime viewing area by about 10 miles. So, heading further south from there, a minimum of 10 miles, should give a better view. For more accurate information from NASA, go to the following site: https://eclipse2017.nasa.gov/eclipse-maps. That should allow you to see good detail on all viewing options across the US. (As always, look for the .gov address in any link to be sure you are getting official albeit accurate eclipse information.)
