Not far away in December 2011. On Saturday, people can get to see a rare sight in the morning to watch the sun and moon, as well as in Eclipse. Alaska, Hawaii, Canada and the north-west Australia, New Zealand and the countries of Central and East Asia, the ring the second year in a total lunar eclipse can be.
East Zone of the United States and Canada, see, or only the first steps into the dark of the moon, or skip all the parts of the continent will eto.Tsentralnye setting moon, in the shadow of the Earth's shadow. Lucky in the region of the Rocky Mountains and Plains will see a total eclipse of the moon.
The moon will be completely covered by the southern part of the earth's shadow at 6:06 am PT and quit after 51 minutes.
The term is an unusual sight "selenelion" (or "selenehelion"). This phenomenon will be visible on most of the United States. Selenelion a fad vision than is actually happening. If we recall our lessons science, we know that refraction bends the rays of light when light passes through two media of different density. Atmospheric refraction causes astronomical objects appear higher in the sky than they really are. Therefore, when the sun actually set, we can see the sunset through the refraction in the atmosphere. Selenelion is due to the refraction of light makes the Sun visible though it is not eclipsed by the moon.

In this Saturday for about 5:59 minutes, refraction makes the moon seem to set for people in the U.S. while the sun rises on the other horizon. To the east of the Appalachian Mountains, it will not be seen because, in spite of the moon be above the horizon, when it begins to enter Earth's shadow at 6:33 EST, it will be the first to be met by penumbral shadow, thus hiding the moon before it can to be spied on. This will make the moon look very well in areas such as Boston, New York or Miami.

Those in the Upper Midwest, Heartland of the nation, down in the central part of Oklahoma and Texas will see the shadow creeping shadow almost straight down the face of the moon from its upper extremity. So if you are determined to see this phenomenon, watch from an elevated location as necessary and horizons have to be away from tall buildings or obstructers view.

For those who are in India, second lunar eclipse will be visible to the state of Orissa at 5 pm. At 6 pm the Moon will enter the shadow and the shadow of the moon will be visible. He will remain in the shadows until 7:30 pm. Suvendu Patnaik, deputy director of the planetarium Pathani Samantha said: "The shadow will completely cover the Moon at 7:36 pm, when the brightness of the moon will be reduced to less than 40 percent of its original brightness. It will start leaving around 8:27 in the evening shadows and completely withdraw from her about 9:47 pm. "

This will be the second total eclipse of the moon this year. The first was on June 15. A lunar eclipse is common and occurs at least once a year and can grow to four times a year. A total of seven eclipses can be seen in a year. Unlike a solar eclipse, lunar eclipse can be seen with the naked eye, and it is also perfectly safe to go out into the light eclipsed the moon! It also will be the second this year.
