North Americans gathered to watch four-and-a-half minute long total solar eclipse

Throngs of skywatchers across North America have gazed upward at a blackened sun in the midday dusk, celebrating with cheers, music and matrimony the first total solar eclipse to darken the continent in seven years.

From a Mexican beach resort near where the eclipse made landfall to the banks of the Ohio River to the roaring cascades of Niagara Falls on the US-Canadian border crowds catching a glimpse of eclipse “totality” reacted with jaw-dropping expressions of awe and joy.

In Russellville, Arkansas, a town of roughly 30,000 residents near the state’s only nuclear power plant, almost 400 couples tied the knot by the shadow of the moon in a mass wedding event dubbed “Elope and the Eclipse.”

At least two weddings and one marriage proposal were known to have taken place among roughly 2000 people who assembled at Niagara Falls State Park despite overcast skies.

The dreary weather subdued the experience until clouds momentarily parted to reveal the last 30 seconds of totality, and the crowd went wild, cheering and shouting, “It’s so beautiful.”

As the skies began to brighten again, a band played out the retreating lunar shadow with a rendition the R.E.M.’s 1992 hit song Man on the Moon.

Where clear skies prevailed, observers along the direct path of the eclipse were treated to the rare spectacle of the moon appearing as a dark orb creeping in front of the sun, briefly blocking out all but a brilliant halo of light, or corona, around, the sun’s outer edge.

It was first total eclipse to sweep across a large swath of North America since 2017.

As totality unfolded at a campground in North Hudson in upstate New York, hundreds of people shrieked with excitement.

Mexico’s beachside resort town of Mazatlan was the first major viewing spot for totality. Thousands in solar-safe eyewear perched in deck chairs along the coastal promenade, and an orchestra played the “Star Wars” movie theme as skies darkened under the approaching lunar shadow.

The crowds burst into cheers, applause and whistles when the eclipse reached totality.

The period of totality, lasting up to four-and-a-half minutes depending the observer’s location, was ushered in by a number of other eerie eclipse effects. Some stars twinkled at midday as dusk abruptly descended, sending temperatures dipping and faint waves of “shadow bands” flickering over the landscape. Birds and other wildlife sometimes fall silent and still.

Eclipse fans travelled from far and wide hoping to glimpse the phenomenon somewhere along the “path of totality” stretching 4000km from Mexico’s Pacific Coast through Texas and across 14 other US states into Canada.

Overcast skies across much of the United States added an extra challenge for many.

Laura and Brian Uzzle were awaiting the eclipse on the banks of the Ohio River between Indiana and Kentucky on Monday after cloudy forecasts prompted the Denver-based couple to abandon their initial plan of viewing it in Texas and book last-minute flights and rental cars several hundred kiloemtres away.

Laura Uzzle, 56, said she was excited to experience the eclipse by a riverbank teeming with birds and insects.

“Even the wildlife changes,” she said. “It’s a complete sensory experience.”

At up to four minutes and 28 seconds, the total eclipse surpassed the duration of the 2017 one that lasted upwards of two minutes and 42 seconds.

Monday’s total eclipse rolled through more densely populated regions than seven years ago, a corridor averaging 185km wide encompassing such major cities as San Antonio, Austin and Dallas, Texas; Indianapolis, Indiana; Cleveland, Ohio; Erie, Pennsylvania; and Montreal, Quebec.

About 32 million people in the United States live within the path of totality, with federal officials having predicted another 5 million people would travel to be there.
