Lunar Libration 2006
An extremely cool video animation of lunar libration throughout 2006. This shows not only how the Moon comes closer and recedes in its orbit, but also the "wobble" or Libation it has.

I wondered at the title whether this might be something menstrual; but in fact it's libration.
Oops. Corrected :)
Awesome. My favourite heavenly body put on a good show last year.eh? Last night's moonrise over Blighty was spectacular too - huge, full, glowing amber.
