quote:
The late day sun will transform into a glowing ring in southwest Oregon, Northern California, central Nevada, southern Utah, northern Arizona and New Mexico and finally the Texas Panhandle where it will occur at sunset on Sunday. For 3 1/2 hours, the eclipse follows an 8,500-mile path. Viewing, from beginning to end, lasts about two hours. The ring phenomenon lasts as long as 5 minutes depending on location.
