Millions in North America from Mexico to Montreal view solar eclipse

Millions of people in Mexico, the U.S. and Canada experienced a total solar eclipse on Monday.

The spectacle occurs when the moon passes between the sun and the earth, completely obscuring the sun and leaving only a bright ring of fire visible.

Beginning over the Pacific Ocean, the core shadow stretched across northern Mexico, crossed the U.S. from Texas north-eastwards to Maine, grazed south-east Canada and ended over the North Atlantic.
