No, the moon is actually moving away from the Earth

It gets closer and further away. Its apparent size varies quite a bit, in fact.

SC - true, but the overall movement is away from the Earth.

Of course - lots of whacky theory about why, recently too.
But I was thinking that the question was asking about how the moon seemed particularly big that night.

In addition to what has already been said, the closer to the horizon you can see a full Moon, in perfect atmosferic conditions of visibility, the greater you perceive it (optical illusion already treated in this forum, don't remember when).

Tonight's Moon is biggest in 15 years [12 December 2008]

 by Maggie McKee

The full Moon will loom larger in the sky on Friday than it has since 1993, as it will be nearly as close as it ever comes to Earth in its orbit.

The Moon does not orbit Earth in a perfect circle. Instead, it follows an elliptical path that brings it 50,000 kilometres closer to our planet on one side of its orbit (called perigee) than the other (apogee).

On 12 December, the Moon will enter its full phase, when its disc appears completely illuminated by the Sun, just four hours after reaching its closest point to Earth. This will make it 14% bigger and 30% brighter than other full Moons in 2008, though the difference will be hard to distinguish by eye
