Nice writeup at wikipedia:
http://en.wikipedia.org/wiki/28_August_2007_lunar_eclipse
which says:

A total lunar eclipse will take place on August 28, 2007, the second
of two lunar eclipses to occur in 2007. The Moon is expected to enter
the Earth's penumbra at 07:53:39 UTC. The first partial phase will
begin in earnest at 08:51:16 UTC when the Moon enters the Earth's
umbra.

The total phase is expected to begin at 09:52:22 UTC and end at
11:22:24 UTC-- a length of 1 hour, 30 minutes, and 2 seconds. This is
a typical duration for such an event. The umbral magnitude is
expected to be 1.4760.

The second partial phase is expected to begin at 11:22:24 UTC when
the Moon starts to slip out of the Earth's umbra. The partial phase
of the eclipse will end at 12:23:30 UTC, with the penumbral phase
expected to terminate at 13:21:01 UTC.

Oceania will be favored for the eclipse, whence the Moon will be at
its zenith over French Polynesia at the moment of greatest eclipse,
10:37:22 UTC. Alaska and the Pacific regions of the continental
United States will also witness the whole event, along with most of
eastern Australia, New Zealand and all in 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 will
enjoy 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 will miss out on the beginning of the eclipse,
because the eclipse will occur at or close to moonrise in those
regions. Greenland, Europe (including western Russia), Africa,
western Asia, western Central Asia, and western South Asia are
expected to miss the eclipse completely.
