  13. Geometry and Rhythm

  14. The Sun-Earth-Moon System Key Points • Both the Sun and Moon are 1/2 in diam. • This is the same as a dime held at 6 1/2 ft. • Our horizon rotates 15/hr. • The Moon moves 1 diameter / hr (2500 MPH) thru stars. • The Moon rises 50 minutes later each day. • The Earth moves 8 diameters / hr (65,000 MPH) around the Sun.

  15. The Geometry of Shadows Key Points • Umbra is the area of full shadow.Total Eclipse • Penumbra is the area of partial shadow.Partial Eclipse • Antumbra is the region beyond the Umbra. Annular Eclipse

  16. To Sun

  17. Lunar Rhythms • Synodic Month 29.5 days (full to full) • Revolution Period 27.3 days • Rotation Period 27.3 days • Draconic Month 27.2 days (crossing the ecliptic) • Anomalistic Month 27.6 days (closest to closest) • Saros Cycle 18 yrs 11.32 days (223 synodic months)

  18. Lunar Rhythms Key Points • Solar Eclipses require a New Moon. • Lunar Eclipses require a Full Moon. • The Moon’s orbit is tilted 5° (9 diameters) • Four primary rhythms: New to New, rising and falling, in and out, & yearly seasons • Eclipse Seasons occur every 6 lunar months because of the first two rhythms. • All four rhythms repeat every 18 years.
