O Moon!

Did you enjoy last month's amazing full moon? It was the biggest, most wonderful and mysteriously luscious moon of 2008.

Guess what? Tonight - January 10th - the biggest full moon of 2009 is coming.

Johannes Kepler explained the phenomenon 400 years ago. The Moon's orbit around Earth is not a circle; it is an ellipse, with one side 50,000 km closer to Earth than the other. Astronomers call the point of closest approach "perigee," and that is where the Moon will be this weekend.

Perigee full Moons come along once or twice a year. 2008 ended with one and now 2009 is beginning with another. It's the best kind of déjà vu for people who love the magic of a moonlit landscape.

January is a snowy month in the northern hemisphere, and the combination of snow + perigee moonlight is simply amazing. When the Moon soars overhead at midnight, the white terrain springs to life with a reflected glow that banishes night, yet is not the same as day. You can read a newspaper, ride a bike, write a letter, and at the same time count the stars overhead. It is an otherworldly experience that really must be sampled first hand.

Another magic moment happens when the perigee Moon is near the horizon. That is when illusion mixes with reality to produce a truly stunning view. For reasons not fully understood by astronomers or psychologists, low-hanging Moons look unnaturally large when they beam through trees, buildings and other foreground objects. This weekend, why not let the "Moon illusion" amplify a full Moon that's extra-big to begin with? The swollen orb rising in the east at sunset may seem so nearby, you catch yourself reaching out to touch it.

You won't be the only one. Even at perigee, the Moon is 360,000 km away, yet the distant beauty beckons to poets, stargazers and NASA with equal force: "Come back," it seems to say, "I'm really not so far away."

I'll be looking at that moon tonight with an especial fondness.

Join me tonight for communion and moonlit sparkles. I can feel it already.
