En, a szerz?, ezt a m?vemet ezennel kozkinccse nyilvanitom. Ez a vilag minden reszen ervenyes. Egyes orszagokban ez jogilag nem lehetseges. Ha igy van, akkor: Jogot adok barkinek, hogy barmilyen celbol , feltetel nelkul hasznalhassa ezt a fajlt, kiveve a torveny altal kotelez?en el?irt felteteleket.

Technical

• Book: "Astronomical Formulae for Calculators, 4th edition", Jean Meeus, 1988, published by "Willmann-Bell, Inc"
  • Chapter 30 "Position of the Moon"

Source bitmap for projection from NRL's Clementine Spacecraft:

• USGS: Global simple cylindrical projection at 10 km/pixel.

• Animation
  • 50 frames were created, equally spaced in time.
  • Period used: 27.21222 days (Draconic month of nodes)
  • Animation began and ended at Apogee to minimize "jumping" when cycles back to the start.
  • New moon given an unreal 1% intensity "Ambient light" to show motion in all phases.
  • View assumed from the center of the earth. (Geometrically impossible, but best demonstration of monthly libration caused by moon's motion versus the shorter daily libration that would be included from the surface of the earth.)
