In the last animation , you may have noticed times when the moon moved between the Earth and the Sun. When this happens, the moon blocks some of the sun's light that would ordinarily hit the earth-the moon casts a shadow on the earth. If your green city is in the moon's shadow, you'll see the sun being blocked! What the sun, moon, and earth are doing. What you would see from your green city In this animation, the left frame shows a situation from the last animation where the moon has moved between the sun and the earth. AND, your green city has rotated in a position to witness this event! The right frame shows you what you would see from your green city, looking up at the sun. The dark "hole" in the Sun is the Moon's shadow cast down upon you. The Moon blocks the Sun's light during an eclipse. Lots of such eclipses happen, it's just rare for your city to have rotated in the right position to see it! Click here to see a view of it all from the Moon...

Translation of Sahih Bukhari, Book 18: Eclipses Volume 2, Book 18, Number 150: Narrated Abu Bakra: We were with Allah's Apostle when the sun eclipsed. Allah's Apostle stood up dragging his cloak till he entered the Mosque. He led us in a two-Rakat prayer till the sun (eclipse) had cleared. Then the Prophet (p.b.u.h) said, "The sun and the moon do not eclipse because of someone's death. So whenever you see these eclipses pray and invoke (Allah) till the eclipse is over."

Restyled front and rear bumper fascias distinguish the Eclipse models for 2009, with the GT also now sporting a new large rear spoiler. The GT model also gains standard high intensity discharge (HID) head lamps for 2009, further sharpening front styling while aiding visibility for nighttime driving. The 2009 Eclipse GT will announce its presence a bit more strongly for 2009, thanks to a new dual exhaust system that yields a more powerful sound while also boosting horsepower to 265 (up from 263). Already equipped with a full array of proven safety technology, the Eclipse GT for 2009 gains Active Stability Control (ASC) as standard equipment. Newly styled single-color front and rear bumper fascias lend a more defined appearance to the Eclipse GS, while the new two-tone bumper fascias for the GT model further emphasizes its road-hungry stance. The "attainable exotic" design of the fourth-generation Eclipse is further underscored for 2009 by the availability of three new colors, Maizen Blue pearl, Quick Silver metallic and Solar, a vibrant new yellow. Models with the standard cloth interior feature upgraded fabrics.

A lunar eclipse occurs when the moon passes through the shadow of the earth. A lunar eclipse can last up to an hour and a half. During a lunar eclipse the moon may turn a reddish color. It is not dangerous at all to look at a lunar eclipse because the moon does not make its own light. Animation by Stephen Gray using photos © James Funkhouser Photograph © James Funkhouser A Solar Eclipse occurs when the moon goes in front of the sun and blocks most of the sun's light from the earth. During a total eclipse all you can see from earth is a ring of light around the moon which is part of the sun the moon did not cover. It is dangerous to look at a solar eclipse directly, even if you have sun glasses or smoked glass. It is better to view solar eclipses through a pin hole projector.

Anybody who has experienced nature's most awesome and unusual phenomenon never forgets it. We have met people who have seen total eclipses by accident and their reaction is always one of amazement. Although the entire eclipse can last for a couple of hours, the spectacular total phase lasts only for a few minutes. The maximum duration of totality is just over seven and a half minutes. For any one location, total eclipses of the sun occur rarely; on average, once every 410 years or so. In our home city, London , the last two total eclipses of the Sun occurred in the years 878 and 1715; the next is not due until 2151! In a larger area, they are more common. For England, the last was in 1999 and the next in 2090. For the Earth as a whole, total solar eclipses occur roughly seven or eight times every ten years. If we are to see one we must travel. Kryss has now experienced ten; Talaat seven. One of those was clouded out but was still worth being present for.

" - Maurice Allais, 1988 Nobel autobiographical lecture. August 6, 1999: The natural phenomenon of a solar eclipse has historic ally brought kings to assemble armies and, in the modern era, brought camera-toting astronomers to remote locations around the world. On August 11, a solar eclipse will bring scientists together in an effort to solve a 45-year mystery. Right : When the Moon eclipses the Sun, the solar corona becomes visible. The corona is faint compared to the Sun, so it can only be seen when the Sun is blocked from view. Jean Bernard Leon Foucault, with the physicist Armand Fizeau, took the first clear photograph of the Sun in 1845. The mystery lies in the question: Does a solar eclipse somehow affect a Foucault pendulum? In 1954, Maurice Allais reported that a Foucault pendulum exhibited peculiar movements at the time of a solar eclipse. If true, his finding raises new questions about the nature of such phenomena.

"Unemployment, salaries, immigration – those are the things that matter," says Mr. Rodr­guez, a civil servant. It wasn't expected to turn out this way. Only a few months ago, the March 9 vote looked set to hinge on broad political questions about national identity, regional autonomy, and how to deal with the Basque separatist group ETA. In addition, it was seen as a referendum of sorts on Prime Minister Jos© Luis Rodr­guez Zapatero's sweeping social reforms on gay marriage, divorce, and other issues, which have riled conservatives and the Roman Catholic Church. Then the economy faltered, and everything changed.

Speculation on the study of Stonehenge have continued unabated from the time that it was first mentioned in the literature shortly after the Norman Conquest (1066). Evidence indicates that Stonehenge, built during the same era as the Great Pyramid of Egypt, was a brilliantly conceived astronomical observatory. Certain holes were apparently used as an eclipse predictor. "And on that day," says the Lord God, "I will make the Sun go down at noon, and darken the Earth in broad daylight."

These events were viewed with fear and dread in the past and, even today, still thrill. There is a lot of special vocabulary involved in eclipses but there is a way to keep from being confused. The eclipse is named for the object that is being eclipsed, or obscured. In a solar eclipse you observe the Sun (using only safe methods, of course). You will see the Sun with a piece apparently cut out of it. In a lunar eclipse you observe the Moon. A portion of its surface will be obscured. Another way to avoid confusion is to consider the time at which you will be viewing the eclipse. Because of the geometry described below, you can only view a solar eclipse when the Sun is up. You view lunar eclipses when the Moon is up. Eclipses occur when the Sun, Earth and Moon line up. They are rare because the Moon usually passes above or below the imaginary line connecting Earth and the Sun. In a solar eclipse the Moon passes directly in front of the Sun. This can only happen when the phase of the Moon is "new." That occurs because, for Earth-based observers, the far side of the Moon is illuminated while the side facing Earth is in darkness. The Moon, like any sphere, casts a shadow. A solar eclipse occurs when that shadow sweeps across Earth. The black cone is called the

Other Pages A solar eclipse occurs when the Moon, during its monthly trip around the Earth, happens to line up exactly between the Earth and the Sun. The glory of a solar eclipse comes from the dramatic view of the Sun's corona, or outer atmosphere, which we can see only when the brilliant solar disk is blocked by the Moon. The corona is not just light shining from around the disk. It is actually the outermost layer of the solar atmosphere. Although the gas is very sparse, it is extraordinarily hot (800,000 to 3,000,000 K), even hotter than the surface of the Sun! The corona shows up as pearly white streamers, and their shape is determined by the Sun's current magnetic fields. Thus every eclipse will be unique and beautiful in its own way.

40. SOLAR ECLIPSES Experiences and images of total eclipses of the sun from 1932 to 1998. http://home.columbus.rr.com/gfoley/eclipse.html

MY SOLAR ECLIPSES All images on this page are by Gerard M Foley. Most were taken on slide film (Kodachrome or Ektachrome) and scanned commercially into a PhotoCD. Others were taken with an Olympus D600L digital camera. All were finished for this webpage in PaintShopPro 5.01. To see a full size image, click on the thumbnail. The first total eclipse I saw was in North Conway, NH, on August 31, 1932. Unhappily I have no pictures. Totality occurred in a "mackerel" sky, high thin clouds that afforded a fairly good view of the inner parts of the solar corona. In 1954 our family went to Copper Harbor, Michigan, on the Keweenaw Peninsula in Lake Superior. This was the easternmost point in the United States on the path of totality of that year's solar eclipse. A few minutes before totality, the clouds which had covered the eastern horizon (in the first picture below) lifted, only to be replaced by the fog you see in the next two, taken just before and just after totality. The "perfect eclipse" came in 1970, in Williamston, NC. On the left below are the dozens of optical instruments set up behind the Holiday Inn and the brilliant blue sky on the day of the eclipse. We could go into a motel room to see the eclipse in Mexico City on color television, then come out to see for ourselves. On the right are my wife and I and the 800mm. f8 lens with which I took the five frames below. Here are the "diamond ring" at the beginning of totality, three successively longer exposures of the eclipsed sun, and the "diamond ring" at the end of eclipse.
