August 21 is exactly one year before the 2017 eclipse of the Sun which will sweep across one country and one country only -- the US. On a Monday morning (Aug. 21, 2017) this "All-American" eclipse (as it's being called) will begin on a beach in Oregon and cross the country diagonally to end in the afternoon on a beach in South Carolina. See the map below.
The eclipse will be total (moon covering the Sun completely) only in a path about 60 miles wide and we expect huge crowds and traffic jams in that zone. The rest of North America (500 million people) will see a partial eclipse, with a big bite taken out of the Sun. Special eclipse glasses or ways of projecting an image of the Sun will be needed to see the partial eclipse safely.
The full story,in everyday language, with a map and times for major cities, and safe viewing guidance, can be found in a free 8-page excerpt from a book, called Solar Science, that Dennis Schatz and I wrote for teachers. It is at: http://bit.ly/2bkGSvA
There is a national committee that I serve on trying to arrange a good experience with the eclipse for as many people as possible. Wish us luck! Dennis and i are also working with science teachers, libraries, and science and nature museums to become centers of eclipse information for their communities.
I'll say more about preparations for the eclipse on this page as the year goes on. But for now, you may want to note the date and if you have friends or relatives in the total eclipse zone, be extra nice to them starting now.
And thanks to Prof. Tyler Nordgren of the University of the Redlands for permission to use his cool poster.

For those of you who are teachers, or who know a teacher, we will be doing a webinar on how to prepare yourself and your students for the eclipse. For more see:
