A partial lunar eclipse occurred at 1820 Universal Time (UT) on Monday, August 7, and was visible to observers in Asia, Australia, and Indonesia. Parts of Western Europe saw the fullmoon rise at sunset with its western limb in Earth's shadow.

Earth's umbra, the innermost and darkest part of its shadow, covered the Moon's southern quarter, including the crater Tycho.

The eclipse was only partial and was not visible anywhere in North America, which was in daylight when it occurred.

For skywatchers in Asia, Australia, and Indonesia, the eclipse will take place in the early morning hours of Tuesday, August 8.

This eclipse and the upcoming total solar eclipse on Monday, August 21 are related in that they are both part of a single eclipse season. Eclipse seasons last slightly over one month and involve at least one lunar eclipse at the Full Moon and one solar eclipse at the new Moon.

Both lunar and solar eclipses occur only when one of the Moon's two orbital nodes, the points at which an object crosses a plane of reference, crosses the ecliptic or path of the Earth in its orbit around the Sun.

During Monday's lunar eclipse, the Moon crossed the ecliptic from north to south. Two weeks later, at the solar eclipse, it will cross the opposite way, from south to north.

SLOOH.com, an online robotic telescope service, broadcasted the lunar eclipse live on Monday between 11:45 AM and 3:20 PM EDT (1545 to 1920 Universal Time).

Astronomy website Space.com will also provide a live broadcast of SLOOH.com's coverage, which will include live feeds from observatories in Asia, Africa, and Australia, along with guest commentaries.
