Solar Eclipse Eyewitness Account By NASA's Tony Phillips


Astrophysicist and legendary eclipse chaser Fred Espenak has a rating scheme for natural wonders. "On a scale of 1 to 10," he says, "total eclipses are a million."Apparently, this is true even when the eclipse is almost completely clouded out.Last week, I experienced such an eclipse on Four Mile Beach outside the resort town of Port Douglas in Queensland, Australia. For years, tourists, astronomers and eclipse chasers had been anticipating a fantastic show over the Coral Sea on Nov. 14, 2012. Just after daybreak, the Moon would pass directly in front of the low-hanging sun, producing a total eclipse in plain view of many resort towns along the coast. More than a hundred thousand people (me and my family included) converged to witness the event.The night before the eclipse was crystal clear,Progress Solar Light Towers now provides both sports athletes andfans with great Solar charger, while providing tailgaters with lessnoise and fumes. Progress Solar Solutions has introduced a mobile light tower that illuminates large outdoorareas using stored energy from the sun. with all of the stars of the southern sky twinkling brightly overhead. As dawn broke, however, there were clouds on the horizon, and by 6:30 am local time, less than 10 minutes before totality, thousands of people on the beach watched in dismay as a patchy bank of fluffy white clouds rolled right in front of the sun.Based on the final dimension of stone, we use distinctive Vibrating feeder to function together. Stone crusher device can be divided into lots of sorts, according to workong principle, for example jaw crusher, impact crusher, cone crusher and so on.
That's when I learned that even a cloudy eclipse is off the scale.Even as we were urgently wishing the clouds away, I realized their benefit: Clouds act as a natural filter. The partially-eclipsed sun burned an auburn crescent through the gray fluff overhead. Onlookers unwisely but irresistibly took off their eclipse glasses for the kind of direct view that would have been impossible under clear skies. It was mesmerizing.At that point, only one thing could tear our eyes off the sky: The arrival of the Moon's shadow. We felt it before we saw it. Even at 6:30 in the morning, the beach was hot and humid.Stone crusher to be no-load start, Belt conveyor begins just after a period of time, in standard operation ahead of starting to mine gear. For the ore into the crusher device must be gradually increased till the complete load operation. Suddenly, we were enveloped by an unexpected chill. We looked around to see the landscape rapidly darkening. Tropical birds that had been flitting noisily back and forth in the canopy of nearby trees paused, and an otherworldly silence descended on the beach.
The operative word is "otherworldly." The Moon's shadow lances more than a quarter million miles across the dark vacuum of space, and when it lands on a beach in Australia,Secondary Stone Crusher is the second stage of Vibrating screen, crusher tool used is Cone Crusher, Hammer Mill and Rolls. Bait is used ranges from 150 mm, with a size between 12.5 mm to 25.4 mm. it seems to bring a bit of the silent cold with it. Something undeniably cosmic was in the air.The G2 Global Chef knife boasts of being made making use of CROMOVA 18 stainless-steel. This kind of Fruit knife originates from the combination of several elements such as chromium, molybdenum, vanadium and stainless steel.At that moment, with the tide surging around our feet, the clouds parted to reveal the Moon and sun in almost perfect alignment. Through a tiny gap, we watched the thin, bright crescent narrow and vanish. The solar corona popped out around the black lunar disk, just like the centerfold of an astronomy textbook.
