Live Updates: Millions Await the Eclipse’s Dark Path Across a Continent

Live Updates: Millions Await the Eclipse’s Dark Path Across a Continent

For centuries, people have strived to catch a glimpse of solar eclipses. From astronomers with custom-built photography equipment to groups huddled together wearing specialized glasses, this spectacle has captivated the human imagination.

In 1860, Warren de la Rue took what many sources consider to be the first photograph of a total solar eclipse. He recorded it in Rivabellosa, Spain, using an instrument called the Kew Photoheliograph. This telescope and camera combination was built specifically for photographing the sun.

Forty years later, Nevil Maskelyne, a magician and astronomy enthusiast, filmed a total solar eclipse in North Carolina. However, the footage was lost and was only released in 2019 after it was rediscovered in the archives of the Royal Astronomical Society.

Telescopic vision

For scientists and astronomers, eclipses not only provide an opportunity to view the Moon’s umbra and the Sun’s corona, but also make observations that advance their studies. Many observatories or friendly neighbors with telescopes also make their instruments available to the public during a solar eclipse.

Fredrik Hjalmar Johansen, Fridtjof Nansen and Sigurd Scott Hansen observed a solar eclipse during a polar expedition in 1894.

Women from Wellesley College in Massachusetts and their professor tested the equipment before their eclipse trip (to “catch old Sol in the act,” as the original New York Times article put it) to New London, Connecticut, in 1922 .

A group from Swarthmore College in Pennsylvania traveled to Yerbaniz, Mexico, in 1923 with telescopes and a 65-foot camera to observe the solar corona.

Dr. JJ Nassau, director of the Warner and Swasey Observatory at the Case School of Applied Science in Cleveland, was preparing to travel to Douglas Hill, Maine, in 1932 to study a solar eclipse. An entire freight car was required to transport the facility’s equipment.

Indirect light

If you see people sprinting into your local park on Monday with pieces of paper or a cardboard box on their head, they’re probably planning to reflect or project images of the eclipse onto a surface.

Cynthia Goulakos demonstrated a safe way to observe a solar eclipse in Lowell, Massachusetts in 1970 by using two pieces of cardboard to create a mirror image of the shadowed Sun.

Another popular option is building a pinhole camera. This woman did this in Central Park in 1963 using a paper cup with a small hole in the bottom and a dual lens reflex camera.

In 1967, amateur astronomers observed a partial solar eclipse from the roof of the Empire State Building, which was projected onto a screen by a telescope.

In 1970, Irving Schwartz and his wife reflected a solar eclipse on a piece of paper in Central Park by holding binoculars to the edge of a trash basket.

In 1979, children in Denver used cardboard observation boxes and pieces of paper with small holes to view projections of a partial solar eclipse.

Staring at the Sun (or How Not to Burn Your Retina)

Eclipse watchers have used different methods to protect their eyes over the years, some safer than others.

In 1927, women gathered at a window of a building in London to watch a total solar eclipse through smoked glass. This was popularized in France in the 18th century, but fell out of favor when doctors began writing works on children whose vision was impaired.

Another trend was to use a strip of exposed photographic film, as seen below in Sydney, Australia, in 1948 and in Turkana, Kenya, in 1963. This method, even suggested by the Times in 1979, has since been declared unsafe.

Solar eclipse glasses are a popular and safe way to view the event (as long as you use models that meet international safety standards). There have been various styles over the years, including these large handheld units found in West Palm Beach, Florida in 1979.
