Solar Eclipse
Contest Directions: Northern Europeans don't see much of the sun in January, and this morning our star was obscured even more than normal. Thanks to a much-anticipated partial solar eclipse, it was reduced to a crescent. The eclipse was visible in parts of Europe, Asia and the Middle East, but its effects were most dramatic in Sweden, where as much as 85 per cent of the sun's disc was obscured. It was also visible as a minor partial eclipse over Northern Africa and the Arabian peninsula. Ancient Chinese believed solar eclipses happened when a giant dragon ate the sun. They performed the special rituals to chase the dragon and make him release the Sun. Ancient Vikings legend says the two chasing wolves, Skoll and Hati, were to blame for making the sun disappear from the sky.
Photoshop a solar eclipse any way you wish. Some examples are: Show how companies can use a solar eclipse for commercial purposes - advertising their brands and products, show how politicians / political parties may use a solar eclipse to increase their ratings. Feel free to create advertisements / billboards / magazine covers for the above. Solar eclipses in movies, paintings, album covers, etc. Either partial or total solar eclipses are acceptable in the entries.

This contest is fueled by the following news: Solar eclipses occur when the Moon travels between the Earth and the Sun and all three of them are lined up. A total eclipse occurs when the Moon blocks the Sun completely and the dark shadow reaches the Earth. It can be observed only along a narrow path of 160 to 320 km wide, which is called the path of total solar eclipse. Just before the total phase of the eclipse one can see several light spots from the Sun on the edge of the uneven Moon disk, called "Baily's beads". Sometimes, right before the eclipse one can see the last bright flash from the Sun – the Diamond ring effect. During the total phase of the eclipse, which lasts on average 2.5 minutes (maximum 7.5 minutes) the sky becomes grey, at this moment it is possible to see stars and planets. One can see the crown too – the outer part of the Sun's atmosphere. When the angular size of the Moon is smaller than the size of the Sun, it does not block the Sun completely and we can see the black silhouette of the Moon surrounded by a ring of sunlight. This is called an annular solar eclipse. The Sun's crown is not visible due to the fact that the Sun is covered only partially. Although the sky might get dark, it will not be enough to be able to see the stars. The Moon's penumbral shadow produces a partial eclipse visible from both sides of a total and annular solar eclipse. The Moon covers the Sun only partially and the sky does not get that dark. The total solar eclipse on June 30, 1973, evidently is the most thoroughly observed eclipse in human history. It's longest duration, which could be observed from Western Africa on the border of Mali and Mauritania, was 7 minutes 4 seconds – which is close to the possible maximum. On board of the English French supersonic airliner "Concord" a group of English, French and American scientists was following the Moon's shadow at an altitude of 17 km, at a speed of more than 3200 km per hour. As a result the observations lasted 74 minutes which is unprecedented. Apart from "usual" studies of the Sun crown and chromosphere, of the influence of eclipses on ionosphere, magnetosphere and atmosphere of the earth conducted during solar eclipses, there have been several unique experiments. For instance, scientists from the Federal Republic of Germany conducted an experiment with the purpose to clarify the existence of gravity waves, which could be the result of such interaction between the Moon and the Sun. A team of American astronomers used solar eclipses to find small hypothetical planets with orbits, within the orbit of Mercury; for over a century there have been attempts to attribute displacements, in Mercury's perihelion to their attraction. A number of scientific discoveries not directly related to Astronomy and Geophysics stand apart. For instance, a group of anthropologists and sociologists visited areas inhabited by Elmolo tribes in Kenya, sun worshippers on the border of Ethiopia, some tribes in the Mauritania in order to observe their behaviour during eclipses, when they had no idea it was coming. The animal world of Africa, including ants, has also been observed in order to find out if changes in the lighting influence anima's cyclic behaviour or maybe it is dictated from within by their physiological nature. Annular solar eclipse - is a solar eclipse which occurs when cone shaped extension of the Moon's shadow crosses the surface of the Earth (the Moon is too far away from the Earth to block the Sun completely). The average length of the Moon's shadow is 373,320 km and the distance from Earth to the Moon on May 20, 2012 is 395507 km, therefore the Moon's shadow cannot reach the surface of the Earth. Thus, the Moon covers only 0.9439 of the diameter of the sun's disk leaving a thin rim visible. In annular eclipse the bright rim of the Sun makes it hard to see the crown or the stars nearby. The instant and the point of greatest eclipse: The instant of greatest eclipse – is the moment when the centre of the Earth is closest to the axis of the Moon's shadow cone during the eclipse. The point of greatest eclipse is the place on the surface of the Earth, in which at the instant of greatest eclipse the phase of the eclipse is maximal. For annular solar eclipse the instant of the longest duration of the eclipse may or may not concur with the instant of greatest eclipse. The longest duration of such an eclipse fall on the beginning or the end of the eclipse path. Correction of Terrestrial Dynamical Time brings small irregularities into the calculation of the parameters of eclipses. This correction characterises fluctuations of the Earth's rotations, caused primarily by the tidal influence of the Moon. Time shift resulting from such fluctuations, is called deltaT, and is calculated in the following way: before 1950 - based on identification and approximation of data from available historical resources; from 1950 until now regular reliable measurements have become available, deltaT of the future is the extrapolation of today's measurements subject to the long-term influence of tidal effects.
