Eclipse mania gripped North America yesterday as a breathtaking celestial spectacle set to be witnessed 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 was sweeping across the United States, before returning 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 was forecast over Texas and northeastern US states.

Mexican President Andres Manuel Lopez Obrador visited Sinaloa to witness firsthand 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 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.

Businesses capitalized on the excitement with special events, while hotels and short-term rentals in prime viewing locations were booked solid for months in advance.

At the Stonehenge II park in Ingram, Texas -- a replica of the prehistoric arrangement of stones in England -- eclipse watchers gathered from across the world.

"Even if it's cloudy it's going to get unbelievably dark, especially with clouds," said Jeff Snyder, a 68-year-old engineer who traveled from California along with his wife and had brought his own telescope.

"Everybody's gonna go freaking nuts and you will hear screams."

In Cleveland, where local officials expected some 200,000 visitors, the Rock & Roll Hall of Fame planned a four-day "Solarfest" of live music.

And in Russellville, Arkansas, more than 300 couples were reportedly set to exchange vows at "A Total Eclipse of the Heart" mass wedding ceremony.

Delta airlines has planned two special flights along the path, while many schools in the zone shut for the day.

Research firm Perryman Group estimates direct and indirect economic impacts of this year's eclipse could reach $6 billion.

Then there's the science. NASA planned to launch a trio of sounding rockets before, during and just after the eclipse to measure changes caused by the sudden darkness to the ionosphere, an upper layer of the atmosphere important for long-distance radio communication.

The eclipse also offered a golden opportunity to study the Sun's corona, the outer layer of its atmosphere which is normally hidden by the blinding light of the surface.

Startling animal behavior has been noted during past eclipses: giraffes have been seen galloping, while roosters and crickets can start crowing and chirping.

Nasa has invited the public to contribute to research through its citizen-science project Eclipse Soundscapes, by recording the sounds of nature.

In humans, eclipses trigger feelings of awe as we confront our own tiny place within the vast cosmic order, research has revealed. Individuals exhibit more "prosocial" feelings towards each other in the aftermath of the shared experience.

Former president Donald Trump, who notoriously gazed directly at the Sun during the 2017 eclipse, attempted to capitalize on the phenomenon by releasing a new campaign ad featuring his larger-than-life head blocking out our star.

Health professionals have stressed however not to follow his example, urging people to use certified eclipse glasses to prevent potentially permanent retinal injury. President Joe Biden made fun of Trump with a social media post saying "Don't be silly, folks."

Only those within the path of totality can safely remove their eye protection and admire the corona peeking out from behind the silhouette of the Moon for a few precious moments.

At least 34 people, including two babies were killed when a contraband fuel depot exploded into flames in southern Benin near the border with Nigeria on Saturday.

According to Beninese Interior Minister Alassane Seidou, “a serious fire occurred in the town of Seme Podji. Another 20 people were seriously wounded in the incident.”

"I can't really give you the cause of the fire, but there is a large gasoline warehouse here and cars, tricycles and motorcycles come from morning to evening,” he added.

Nigeria is a main oil and gas producer where fuel smuggling is very common along its borders, particularly when the government maintains a subsidy to keep fuel prices low.

The majority of the victims were burnt and they could not be not be identified.

It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for 'lorem ipsum' will uncover many web sites still in their infancy. Various versions have evolved over the years, sometimes by accident, sometimes on purpose (injected humour and the like).
