Eclipse across ascending node in Aquarius

A total lunar eclipse occurred on August 28, 2007, lasting just over 90 minutes. The Moon entered the Earth's penumbra at 07:53:39 UTC. The first partial phase began in earnest at 08:51:16 UTC when the Moon entered the Earth's umbra. It exited the penumbra at 13:21:02 UTC.

It is a relatively rare central eclipse where the moon passes in front of the center of the Earth's shadow. It was the "longest and deepest lunar eclipse to be seen in 7 years".[1] [2] In the total lunar eclipse of July 16, 2000 the moon passed within two arc minutes of the center of the Earth's shadow. In comparison this still very deep eclipse was offcenter by over 12 minutes of arc.[3] The next total lunar eclipse of a longer duration was on June 15, 2011.

The lunar eclipse was the second one in 2007. The first one occurred on March 3, 2007.

Viewing

Viewing from Oceania is favoured for the eclipse, because at the moment of greatest eclipse (10:37:22 UTC), the Moon was at the zenith of French Polynesia. The Pacific regions of Canada and the continental United States (including all of Alaska) witnessed the whole event, along with most of eastern Australia, New Zealand and all the Pacific Island regions (except New Guinea), and the tip of the Chukchi Peninsula that includes the town of Uelen, Russia. The majority of the Americas observed an abbreviated eclipse, with moonset occurring at some time during the eclipse. Siberia, far eastern Russia, eastern South Asia, China, the rest of eastern and southeastern Asia, New Guinea, and the rest of Australia missed out on the beginning of the eclipse, because the eclipse occurred at or close to moonrise in those regions.[4]

Luzon (except Visayas and Mindanao) in the Philippines, particularly Metro Manila, missed the rare eclipse entirely, due to clouds in the area due to the rainy season, which saddened many eclipse watchers in the area, but the eclipse was sighted by other amateur astronomers in other parts of the country as the lunar eclipse seen in clear skies. The eclipse was also missed in New Guinea, especially Port Moresby because of clouds. Greenland, Europe (including western Russia), Africa, western Asia, western Central Asia, and western South Asia missed the eclipse completely.


This simulated view of the earth from the center of the moon during the lunar eclipse shows where the eclipse is visible on earth.

Metonic cycle (19 years)

The Metonic cycle repeats nearly exactly every 19 years and represents a Saros cycle plus one lunar year. Because it occurs on the same calendar date, the earth's shadow will be in nearly the same location relative to the background stars.
