Total lunar eclipse on June,15 2011 will be the longest in the next 11 years
Tuesday, 14 June 2011 11:49
The longest total lunar eclipse in the next 11 years will be seen at night from 15 June to 16 June 2011 on all continents, except North America (see a map).

In total, the Moon will remain in the shadow of the Earth about 100 minutes. It will also be the first total lunar eclipse this year, during the eclipse, the Moon will pass almost through the center of the earth's shadow. Lunar eclipse when the moon passes directly through the center of the earth's shadow, is very rare and is called the central total lunar eclipse, the last such eclipse was almost 11 years ago, and the next will only on July 27, 2018.

The emergence of solar and lunar eclipses, due to the peculiarities of the Moon in orbit around the Earth. When the Moon comes between the Sun and Earth, the solar eclipse occurs, and when Earth is between the Moon and the Sun, it is a lunar eclipse. In the case of the solar eclipse of the Moon casts a shadow on the Earth's surface, and in case the lunar eclipse, the Earth casts a shadow on the Moon and the observer on Earth it seems that the shadow of "creeps" to the moon.

On average, solar or lunar eclipses occured every six months, but if the orbit of the Moon lies completely in the Earth's orbital plane, then every two weeks to eclipse occured: at every new moon solar eclipse would occur, and on every full Moon would occur lunar eclipse. But in reality, the plane of the Moon's orbit is inclined to the Earth's orbital plane at an angle of about 5 degrees, because this eclipse occur only when the moon is a new moon or full moon is near the intersection points of the lunar orbit with the plane of Earth's orbit, but this does not happen more often, than semiannually.

The main difference between lunar eclipse and the sun eclipse- that lunar eclipses visible from all over the nighttime hemisphere and solar eclipses are always visible in a very narrow strip on the surface of the Earth. During a lunar eclipse, the Moon as move into the Earth's shadow phase of the lunar eclipse is becoming more and more and more stars become visible to the naked eye. At full lunar eclipse which will occur on June 15, 2011, you can see the faintest stars that are only able to distinguish the human eye.

Upon occurrence of a full lunar eclipse, the Moon takes on a red or brownish tinge. Color of a lunar eclipse depends on the condition of the upper layers of the stratosphere, since it is only transmitted through her light illuminates the moon during a total eclipse. With full lunar eclipses were observed at different times different shades of the eclipse: lunar eclipse on July 6, 1982 was a red, a lunar eclipse on January 20, 2000 had a brownish tint. These colors of lunar eclipses are caused by the fact, that the upper layers of the earth's atmosphere scatter more red rays, so can not observe the lunar eclipse, with shades of green or blue.

According to Richard Keen of the University of Colorado, the lunar eclipse on 15 June 2011 will have a tinge of red color, as in the upper atmosphere have elevated sulfur content, as a result of the ongoing volcanic eruption in Chile. But the most appreciated color of the lunar eclipse can only be those, who will observe the total phase of the lunar eclipse. Observers partial phases of the lunar eclipse should pay attention to the boundary between the illuminated and unilluminated part of the Moon, which will have a vague form of the presence of the Earth atmosphere, the red color of this border can be seen on the high content of sulfur in the atmosphere.

Learn the offensive phase of the lunar eclipse of 15 June 2011 can be based on the scheme, drawn up by scientists of NASA. The diagram shows the position of the Moon relative to the earth's shadow at the moment of contact with the edge of the Earth's penumbra (P1, P4) and the edge of the earth's shadow (U1, U2, U3 and U4), as well as the position of the Moon in the middle of the eclipse. While all the points of contact with the edge of the Earth's penumbra shadow indicated at UT - UT.

Based on this scheme, we can approximately determine the visibility of the lunar eclipse in your point of observation. Based on map, eclipse on 15 June 2011 will not observer on the territory of any country in North America and residents of European countries will not be able to see the full phase of the lunar eclipse. The total phase of the lunar eclipse of 15 June 2011 will also be observed in most parts of Kazakhstan, the republics of Central Asia, the Middle East, Central, Eastern and Southern Africa as well as in India, Thailand and western China.

Total solar eclipse of March 20, 2015 - VIDEO
Solar eclipse predicted for March 20, can disrupt the energy system across Europe. This is the conclusion of operators of electricity. They expect major disruptions in electricity and PE. How to write the Western media, the effect of a natural phenomenon may be unprecedented.

Solar eclipse of March 20, 2015 will happen on the day of the vernal equinox, when the Sun and Moon on the celestial equator intersect in the constellation Pisces. Thereby eclipse symbolically mark the arrival of astronomical spring. eclipse on March 20 will be complete, but the band is the total phase will take place away from the big cities.

Beginning in the North Atlantic, passing through the Faroe Islands and the Norwegian Sea, the Moon's shadow will proceed to the archipelago of Svalbard, and then further north to get away from the world in the area of ​​the North Pole. The maximum duration of the total eclipse reaches 2 minutes 47 seconds at phase 1.044 (namely by an amount the apparent size of the Moon will exceed the size of the Sun). The point of maximum eclipse is located in the Norwegian Sea to the east and north of Iceland, the Faroe Islands.



In Russia eclipse on March 20 will be observed as a private - with the exception of eastern Siberia and the Far East, where the eclipse will not be seen. During a partial solar eclipse, the Moon covers the Sun's disk is not full. At this point, our daystar appears (depending on the location of the observer) in the form of a "chipped" disc, or sickle.

In Moscow, the eclipse will begin March 20, 2015 at 9 hours and 12 minutes according to universal time or 12 hours 12 minutes Moscow. Maximum phase was 0.65, and 2:00 eclipse duration of 14 minutes. This means that most of the Sun disappears behind the Moon.

In St. Petersburg, the phase will amount to 0.78 for the same duration - and the Sun will appear in the form of a sickle. Most phase, which can be observed from the territory of Russia, will be 0.91 - in the Murmansk region on the border with Norway. With this coating the Sun can be seen darkening the sky!

Where to see the total solar eclipse on March 20?

Of course, no matter how unusual a partial eclipse, no astronomical phenomenon does not compare to the beauty and majesty of a full solar eclipse. But the Moon's shadow falling on the ground, narrow, and therefore likely to see in a lifetime total solar eclipse without leaving home town is small. Knowing this, many observers are willing to sacrifice time, money and comfort and go for a complete phase in the most remote and inhospitable corners of the earth - in deserts, mountains, islands.

The total solar eclipse on March 20 will be held away from the continent, but, as already mentioned, two hook archipelago - the Faroe Islands and Svalbard. On the islands of the Sun is completely hidden behind the disk of the Moon just 2 minutes with a little, but the spectacle, believe me, will be worth it!

As the last rays of the Sun will swallow the Moon, the earth suddenly plunged into darkness. animals quiet down, the temperature drops and the sky light up the stars. Closed Sun Moon around the planet Mercury appears (about 20 ° to the west), a little further - Mars. Dazzling bright Venus will turn to the east of the Sun. Right from the Sun will appear and a great summer triangle formed by the stars Vega, Deneb and Altair. To the left of the Sun - will bright winter constellations ... How unusual is to see them rising in the middle of a spring day!

Surprisingly will look and the Sun itself. Around the black disc of the Moon shine spill the solar corona - the outermost regions of the atmosphere of the star. Directly from the disc of the Moon can see the pink prominences. start and finish of the total phase can be observed such beautiful natural phenomena such as Diamond Ring Rosary or Bailey.
