Perigee Super Moon March 2011 Phase?

Tonight's full moon will nearly coincide with the moon's arrival at the perigee phase in its orbit around the Earth.

On March 19, 2011, the moon is expected to be so bright that some sky watchers have dubbed it a super moon.
The moon will be special, it will appear to loom larger and brighter than usual.
At what time is the moon going to be bigger in the sky?

The perigee super moon is slated to rise at 7:38 p.m. A supermoon is bigger and brighter than an ordinary full moon. That's because the moonís orbit around the Earth is elliptical, not round.

Itís quite rare for a full moon to coincide with a perigee. Perigee moons are about 14 percent larger and 30 percent brighter than non-perigee moons.

The moon won't just be at its closest approach to Earth in its elliptical orbit, it will be closer than it has been in 18 years. The last time this occurred was March 8, 1993.
