2017 annular eclipse

Sarmiento (Argentina) (AFP) - Stargazers applauded as they were plunged into darkness Sunday when the moon passed in front of the sun in a spectacular "ring of fire" eclipse.

Astronomers and enthusiasts in Argentina were among the first to see the so-called annular eclipse as it crossed South America shortly after 1200 GMT, on course for Africa.

Staring up through special telescopes, protective glasses or homemade cardboard pinhole devices, they watched the Sun all but disappear briefly as the Moon crossed its path.

The eclipse was most visible in a 100-kilometer (62-mile) band across Chile, Argentina, Angola, Zambia and the Democratic Republic of Congo.

Around 300 stargazers gathered in a remote spot near the southern city of Sarmiento, the point in Argentina where the eclipse left just a bright ring in the dark sky.

Several onlookers blew notes on "erkes," long traditional South American horns.

"I have already seen six annular eclipses and each one was different," said Josep Masalles Roman, an enthusiast who came all the way from Barcelona in Spain.

The spectacle passed on to Angola south of the town of Benguela, then Zambia and DR Congo just before the Sun set.

- Ring of fire -

An annular solar eclipse occurs when the Earth, Moon and Sun line up.

But even when perfectly aligned, the Moon is too far from Earth to completely block out the Sun, creating instead the impression of a fiery ring.

Terry Moseley of the Irish Astronomical Association warned that viewers should not observe the eclipse with the naked eye.

According to the Astronomical Society of Southern Africa (ASSA), the eclipse can be safely observed using a basic pinhole projector.

Punch a tiny hole in a piece of paper with a sharp pencil, hold it into the Sun, and project the image onto a second sheet.

The gaps between tree leaves make for a similar effect on the ground, says the ASSA website, calling this "the coolest and safest way to watch a solar eclipse".

"As about 90 percent of the Sun is covered, you'll notice a distinct drop in temperature and brightness, and a change in the quality of the light which is hard to describe," Moseley told AFP.

- Animal behavior -

Locals in the province of Chubut around Sarmiento said they noted changes in the height of the tide and animals acting unusually.

Experts say that as the day darkens, birds and animals enter a night-time routine, thinking sunset is nigh.

At the height of the eclipse the Moon is right in the middle of the Sun, leaving a perfect ring of light around the edge.

It takes about two hours for the Moon to move across the face of the Sun, but the "ring of fire" peak lasted a mere minute.

Starting in the southeast Pacific Ocean at sunrise, the eclipse passed over southern Chile then Argentina before sweeping over the South Atlantic.

At sea, the eclipse peak was to last 44 seconds and "only be visible to any ships that happen to be in the right place at the right time," said Moseley.


Bessie Smith

Bessie Smith Biography

Singer (1894–1937)

Jazz and blues vocalist Bessie Smith's powerful, soulful voice won her countless fans and earned her the title "Empress of the Blues."


Bessie Smith - Mini Biography (TV-14; 3:20) A short biography of Bessie Smith, who became known as the "Empress of the Blues." Her distinctive voice made her one of the first jazz singers to appear on records.

Synopsis

Bessie Smith was born in Chattanooga, Tennessee on April 15, 1894. She began to sing at a young age and in 1923 signed a contract with Columbia Records. Soon she was among the highest-paid black performers of her time with hits like "Downhearted Blues." By the end of the 1920s, however, her popularity had lessened, though she continued to perform and made new recordings at the start of the Swing Era. Her comeback and life were cut short when she died on September 26, 1937 from injuries sustained in an automobile accident outside of Clarksdale, Mississippi.

Early Life

Bessie Smith was born on April 15, 1894 in Chattanooga, Tennessee. She was one of seven children. Her father, a Baptist minister, died soon after her birth, leaving her mother to raise her and her siblings. Around 1906, her mother and two of her brothers died and Smith and her remaining siblings were raised by their aunt. It was around this time that Smith began to perform as a street singer, accompanied on the guitar by one of her younger brothers. In 1912, Smith began performing as a dancer in the Moses Stokes minstrel show, and soon thereafter in the Rabbit Foot Minstrels, of which blues vocalist Ma Rainey was a member. Rainey took Smith under her wing, and over the next decade Smith continued to perform at various theaters and on the vaudeville circuit.
By the early 1920s, Smith had settled down and was living in Philadelphia, and in 1923 she met and married a man named Jack Gee. That same year, she was discovered by a representative from Columbia Records, with whom she signed a contract and made her first song recordings. Among them was a track titled "Downhearted Blues," which was wildly popular and sold an estimated 800,000 copies, propelling Smith into the blues spotlight. With her rich, powerful voice, Smith soon became a successful recording artist and toured extensively. Going forward with an idea presented by her brother and business manager Clarence, Smith eventually bought a custom railroad car for her traveling troupe to travel and sleep in.

READ ARTICLE: “The Mother and The Empress: Ma Rainey and Bessie Smith” about Rainey’s influence on the life and career of Bessie Smith.
In her recording career, Bessie Smith worked with many important jazz performers, such as saxophonist Sidney Bechet and pianists Fletcher Henderson and James P. Johnson. With Johnson, she recorded one of her most famous songs, "Backwater Blues." Smith also collaborated with the legendary jazz artist Louis Armstrong on several tunes, including "Cold in Hand Blues" and "I Ain't Gonna Play No Second Fiddle." By the end of the 1920s, Smith was the highest-paid black performer of her day, and had earned herself the title "Empress of the Blues."

Decline and Revival

However, at the height of her success, Bessie Smith’s career began to flounder, due in part to the financial ravages of the Great Depression and a change in cultural mores. In 1929 she and Jack Gee permanently separated, and by the end of 1931 Smith had stopped working with Columbia altogether. However, ever the dedicated performer, Smith adapted her repertoire and continued to tour. In 1933, Smith was contacted by producer John Hammond to make new recordings, which hinted at the coming Swing Era.

Death and Legacy

Over the next few years, Smith continued to perform. However, on September 26, 1937, Smith was en route to a show in Memphis, Tennessee with her companion of many years, Richard Morgan, when he sideswiped a truck and lost control of their car. Smith was thrown from the vehicle and badly injured. She died of her wounds in a Clarkdale, Mississippi hospital. She was 43.
Smith’s funeral was held in Philadelphia a week later, with thousands coming to pay their respects. She was buried in Mount Lawn Cemetery in Sharon Hill, Pennsylvania.
Since her death, Bessie Smith’s music continues to win over new fans, and collections of her songs have continued to sell extremely well over the years. She has been a primary influence for countless female vocalists—including Billie HollidayAretha Franklin and Janis Joplin—and has been immortalized in numerous works. A comprehensive, acclaimed bio on her life—Bessie, by journalist Chris Albertson—was published in 1972 and expanded in 2003. An HBO film loosely based on the book is slated to air in 2015, with Queen Latifah (who also executive produced the project) portraying Smith and Mo'Nique playing Ma Rainey






















Floods along the Mississippi River and throughout the South were not uncommon as Bessie Smith made heartbreakingly clear in her song Back Water Blues, recorded in March 1927, and inspired by a flood occurring more than a year earlier. The flood started in the summer of 1926 with exceptionally heavy rains in the Mississippi basin but did not peak until April the following year. The waters did not subside until August 1927.

The Great Mississippi Flood of 1927 was the most destructive river flood in the history of the United States, with 27,000 square miles inundated up to a depth of 30 feet.
