A total solar eclipse occurs in Mexico before moving towards the US and Canada

Eclipse mania gripped North America on Monday as a breathtaking celestial spectacle observed by tens of millions of people offered a rare convergence of commercial and scientific opportunities — and an excuse to party.

The Moon’s shadow plunged the Pacific coast of Mexico into total darkness at 11:07 am local time (1807 GMT) and swept across the United States at supersonic speed, before it returns to the ocean over Canada’s Atlantic coast just under an hour-and-a-half after landfall.

Festivals, viewing parties, and even mass weddings were planned along the eclipse’s “path of totality,” where the Moon could be seen completely obscuring the Sun for up to a few minutes — weather permitting. Cloud cover played spoilsport over parts of Texas.

Mexican President Andres Manuel Lopez Obrador visited Sinaloa to witness firsthand the eclipse from the resort of Mazatlan, describing the event as a “very beautiful, unforgettable day.”

Thousands gathered in Mexico City, just outside the path of totality. “These are opportunities given by Earth and nature that we must seize,” 29-year-old artist Mariana Juarez told AFP.

This year’s path of totality “These are opportunities given by Earth and nature that we must seize,” 29-year-old artist Mariana Juarez told AFP.

This year’s path of totality is 115 miles (185 kilometers) wide and home to nearly 32 million Americans, with an additional 150 million living less than 200 miles from the strip.

The next total solar eclipse that can be seen from a large part of North America won’t come around until 2044.
