Mid-totality during the lunar eclipse of 21 January 2000. ©Fred Espenak, NASA / GSFC On 28 October British astronomers will be able to see the second total eclipse of the Moon of 2004.
When the total eclipse of the Sun is completed, the shadow of the Moon passes and sunlight appears once again at the western edge of the Sun.
Totality lasts for one hour and twenty-two minutes. The Moon begins its exit out of the Earth's shadow at 11:45 p.m., with a partial eclipse lingering onward for one hour and nine minutes. When the Moon completely leaves the Earth's shadow by 12:54 a.

Total Eclipse (lunar or Solar)
When the umbra part of the Earth's Shadow (lunar eclipse) totally blocks the light being received by the moon, these can only occur during a Full Moon.
total eclipse (lunar or solar): A solar eclipse in which the moon completely covers the bright surface of the sun; a lunar eclipse in which the moon completely enters Earth's dark shadow.

Total Eclipse - When the entire moon enters the Earth's umbra (the darkest part of its shadow), this is called a total eclipse. Partial Eclipse - When only part of the moon enters the Earth's umbra, this is called a partial eclipse.

There are estimated to be perhaps 70,000 TNOs, each at least 100 km across, between 30 and 50 astronomical units from the Sun.
Totality can never last more than 7 min 40 seconds, and is usually a good deal shorter. During each millennium there are typically fewer than 10 total solar eclipses exceeding 7 minutes. The last time this happened was June 30, 1973.

A total eclipse will occur when the observer is located within the umbra of the occulting body.
A total eclipse of the moon occurs on the morning of June 16 (NZST). The moon enters the penumbra just after 5.24 am, NZST. It starts moving into the total shadow of the umbra almost an hour later. By then the moon will be getting low in NZ.
A total solar eclipse, however, is much more spectacular. At totality, the disc of the Sun is completely obscured by the new Moon, and only the ghostly solar corona and perhaps gigantic solar flares are visible around the edges of the Moon.
A total lunar eclipse occurs when the moon passes completely into the umbra. If it moves directly through the center, it is obscured for about 2 hr.
