Millions across North America await total solar eclipse

A total solar eclipse will have millions of people across a heavily populated swath of North America gazing toward the heavens on Monday as the moon completely blocks the sun for more than four minutes in some locales. The eclipse will be viewable, weather permitting, along a path starting in Mexico and then crossing through the United States and into Canada. Eclipse fans are gathering in places along the "path of totality" including the city of Fredericksburg in central Texas, where the total eclipse will occur shortly after 1:30 p.m. (1830 GMT).
