According to National Geographic (http://news.nationalgeographic.com/news/2010/01/100129-biggest-full-moon-2010-mars/):

The biggest full moon of 2010 will rise in the east tonight [...].

January’s full moon is also called the wolf moon, according to Native American tradition associating this month’s full moon with wolves howling in the cold midwinter.

The 2010 wolf moon will appear 30 percent brighter and 14 percent larger than any other full moon this year, because our cosmic neighbor will actually be closer to Earth than usual.

The moon will be at its closest perigee—the nearest it gets to our planet during its egg-shaped orbit—for 2010 at 4:04 a.m. ET Saturday, reaching a distance of 221,577 miles (356,593 kilometers) from Earth.
