Millions across North America await total solar eclipse
A total solar eclipse will occur over a heavily populated area of North America, lasting up to 4 minutes and 28 seconds. The eclipse will be visible along a path starting in Mexico, crossing through the United States, and into Canada. Millions of people are expected to witness the event, with some cities along the path of totality including Mazatlan, San Antonio, and Montreal. Eclipse viewers are advised to use protective solar glasses to prevent eye damage. Eclipse veterans describe the moments before totality as foreboding, with shadows becoming crisp and sunshine taking on an eerie quality.
