8/10 evening, the people of Vietnam and the residents of some parts of the world will be a full lunar eclipse 2nd year. Earth's shadow will completely cover the moon in the period from 17h25 to 18h24.
Lunar Eclipse (total eclipse) will start at 17h25 and the entire moon will turn red. Will be maximized when the moon at 17h54 best tinted red. Many people still or referred to as "blood moon" for this phenomenon.
The reason flushed face turns bright due to him from the sun with all the colors with different wavelengths. When sunlight passes through Earth's atmosphere, due to Raleigh scattering, the shorter wavelengths like blue, purple ... will be the Earth's atmosphere scatters almost entirely, only light towards the red color. At this time, the Earth's atmosphere as a focusing lens as red light through the optical axis direction of the deviation of the shadow created by the Earth and this light has shone the moon as it passes through. Thus, the red moon eclipse takes place when. Except for Europe, Africa and parts of Asia minor, then the remaining regions observed this eclipse. Especially countries in the Americas, Australia and East Asia. However, in Vietnam it's difficult to see a full shot, by the weather and the Moon position compared to the eastern horizon at the time. According to NASA's calculations, in Vietnam, half dark eclipse (penumbral eclipse) will start at 15h15, when the moon enters the Earth's shadow at half, but the half-dark eclipse will be very difficult to identify because the hand moon just a little darker than normal. Start time is 16h14 observations, the Moon will begin on the Earth's shadow began to stage partial lunar eclipse (partial eclipse), the color of the earth's shadow on the moon will move in gradually from dark gray to reddish when the shadows grow. By 18h24, the moon will slowly out of the shadows, the color gradually returned to normal until the moon out of the darkness and ends at 19h34 partial lunar eclipse. This particular eclipse is only noticeable from the start partly because phase takes place when the dark half of the lunar eclipse, the Moon just a bit darker than the usual full moon does not make any difference. Through observations of the Earth's shadow covers the moon's surface, we see spherical Earth. Everyone can observe with the naked eye without any eye protection devices. But will observe eclipses more exciting when using binoculars and small telescopes, to see clearly the red surface of the Moon.
