First total eclipse in 99 years to sweep US
Spectacular phenomenon inspires surge in tourism
The first total solar eclipse to sweep North America in nearly a century will march across the continent on Aug 21, casting a shadow over millions of people from coast to coast.
The event, coined the “Great American Eclipse”, is inspiring a surge in tourism in the United States, along with sky-high prices for travel to key viewing spots and a rise in scams such as counterfeit solar eclipse glasses.
Celebrations are planned nationwide, including weddings timed to coincide with the eclipse and a live Caribbean cruise ship performance of the 1983 hit Total Eclipse of the Heart by the singer herself, Bonnie Tyler.
In a nation that is increasingly divided along political lines, some expressed hope that fascination for this spectacular phenomenon, the first in 99 years, would offer people a chance to unite.
“A large swath of the population will be able to easily see this eclipse,” astronomer James Webb at Florida International University said.
“There are plenty of people out there in this day and age that are denying science, so this is an opportunity to show what we really know about the solar system.”
The total eclipse, when the Moon fully blocks light from the Sun, will be visible from a 113km path that carves through 14 US states. A partial eclipse begins on the northwest coast of the United States shortly after 9am.
The total eclipse reaches the western coastline of Oregon at 10.16am Pacific time, then forges a diagonal path, exiting over South Carolina in the afternoon.
While the darkest shadows will fall over this “path of totality”, a partial eclipse extends far beyond it, and may be visible as far north as Alberta, Canada and as far south as Brazil, weather permitting.
“They’ll see a very shallow, partial eclipse,” said Royal Astronomy Society acting director Robert Massey.
The last time an eclipse crossed from the Pacific to the Atlantic Ocean was on June 8, 1918, when a total eclipse was visible from Washington to Florida.
Experts warn that looking directly at the eclipse can burn the retina, possibly causing lasting blind spots.
Anyone planning to look skyward is urged to wear the proper protective eyewear.
“Probably 100 million people are going to look at this but the dangers of looking at the Sun are real and serious,” said Vincent Jerome Giovinazzo, director of ophthalmology at Staten Island University Hospital Northwell Health.
“The damage can really be permanent and right smack in the centre of their vision,” he said.
