Lunar Eclipse October 18, 2013.

Moon's orbit is inclined about 5 degrees with respect to Earth's orbit around the Sun . A Full Moon usually passes through Earth's shadow , with no eclipse , but two to four times a year, the 5 degree difference comes into play and the Moon passes partially through Earth's shadow . Observers on Earth can see a dim Moon. However, on October 18, 2013 , no part of the lunar disk will be completely in the shadow of the Earth and no part of his disk will appear dark.

The decreased light of the visible disk of the Moon is usually noticeable to a trained eye , especially when a relatively small part of the Moon's disc enters the penumbra .

Even if the Earth blocks sunlight from reaching the Moon during a total eclipse, our planet is much smaller compared to the Sun, and thus indirect sun light still manages to go around the Earth . This sunlight is filtered through the Earth's atmosphere , often releasing light blue waves and leaves a bright red or orange light to land on the lunar surface .

Maximum eclipse will take place at 11:51 p.m. UTC , at which time 76.5% of the lunar disk will be in the penumbral shadow of the Earth. The eclipse will last 239 minutes from 9:51 p.m. to 1:50 UTC.

Viewers of regions in America, Oceania , Europe , Africa and Asia can fully see the event. 2013 Eclipse is one of the four lunar eclipses in a short series of descending node of the lunar orbit .

 The next total eclipse will take place on 15 April 2014

Partial eclipse of the Moon from 25 April 2013.
