It took the last lunar eclipse of the year


12/12/2011

Recently, in the past 2011 superzatmenie Moon passed on Saturday evening. Superzatmeniem this phenomenon is called because the shadow of our land completely hide the lunar disk.

Superzatmenie could see on a clear day the residents of Europe, the U.S. and western regions of Russia. In these regions, the moon hung very low in the sky and looked even more than in the zenith.

The eclipse of the moon occurs when our natural satellite enters the Earth’s shadow. At full coincidence of the orbits of the Earth and Moon eclipses are Earthlings could watch once a month. However, the angle between the moon and the earth’s orbit is 5 degrees, and we were able to see the lunar eclipse, the full moon satellite has to move to a point of intersection of the orbit with the plane of Earth’s orbit. Every year, you can watch one or two of these eclipses. This year’s first lunar eclipse occurred on June 15.

The last eclipse of this year, according to NASA, lasted from 11.33 to 17.30 Greenwich Mean Time and 15.33 to 21.33 Moscow time.

Penumbra of the Earth’s moon touched in 15.33. At this time in North America, the satellite was visible at sunset, and on the European continent - at sunrise. Astronomers and psychologists are still trying to find out why the moon illusion that occurs at the time of the eclipse. The fact that, during an eclipse, when the satellite is above the horizon, and the background are seen buildings and trees visually disk suddenly becomes huge sizes.

When the Moon enters penumbra, she begins to blush, becoming "blood drive." "Bloody" color satellite due process of refraction through the Earth’s atmosphere. In these cases, almost all short-blue and blue light is absorbed, and the orange and red runs, turning the satellite into a bright red color.

Each year in the group eclipse satellite clock may vary, dependent on the concentration of dust in the stratosphere. Moon becomes darker when stored in the stratosphere, such as volcanic dust.

The Earth’s shadow completely covered the moon at 18.06 Moscow time and lasted the full phase of the lunar eclipse of 51 minutes. The whole cycle of the eclipse could be seen all over the world, except for the South-West Africa, South and Central America, Antarctica and Western Europe - in these regions are not able to observe the first phase of the eclipse, and the people of the east U.S. have not seen the final phase of the eclipse.

It was the last eclipse of the year and at the end of such phenomena do not foreshadowed. In total this year could be observed for six eclipses - two total lunar eclipses and four partial eclipses of the sun. The next eclipse will be able to see humans as early as May of next year. The period witnessed an annular solar eclipse.
