Total Lunar Eclipse

Total lunar eclipse  15th April 2014  (source: link)
Lunar eclipse occurs when the Moon passes directly behind the Earth into its umbra (shadow). This can occur only when the Sun, Earth, and Moon are aligned (in "syzygy") exactly, or very closely so, with the Earth in the middle. Hence, a lunar eclipse can only occur the night of a full moon. The type and length of an eclipse depend upon the Moon's location relative to its orbital nodes.


Unlike a solar eclipse, which can only be viewed from a certain relatively small area of the world, a lunar eclipse may be viewed from anywhere on the night side of the Earth. A lunar eclipse lasts for a few hours, whereas a total solar eclipse lasts for only a few minutes at any given place, due to the smaller size of the moon's shadow. Also unlike solar eclipses, lunar eclipses are safe to view without any eye protection or special precautions, as they are dimmer than the full moon.



April 15, 2014 we were able to observe a Total Lunar Eclipse visible in the Pacific Ocean region, including Australia and New Zealand, as well as the Americas.  Subsequent eclipses in the tetrad will occur on October 8, 2014, April 4, 2015, and September 28, 2015.

During a total lunar eclipse, the disk of the Moon took on color appearance from bright orange to blood red and more rarely dark brown to very dark gray, which can be seen with the naked eye. The northern part of the moon noticeably darker than the southern part. Occur during the ascending phase of the moon's orbit, part of lunar saros 122.

Eclipse of the Moon can only take place at Full Moon, and only if, gdyKsiężyc passes through some portion of Earth's shadow. Shadow actually consists of two cone-shaped parts, one For the second nested. The outer shadow or penumbra jeststrefa where Earth blocks some (but not all) of the sunlight. In contrast, the inner shadow or Umbra jestregion where Earth blocks all direct sunlight from reaching the Moon.
